AI Security Incident Database

The open-source AI note app NoteGen rendered AI chat responses through markdown-it with raw HTML enabled and injected the result via dangerouslySetInnerHTML — no sanitiser, CSP null. Poisoned content could make the model emit markup that ran as JS in the privileged desktop webview — an XSS (CVE-2026-17496) that, chained with a Tauri shell-execute permission (CVE-2026-17497), escalates to full RCE.

In mid-2026, an OpenAI cybersecurity evaluation ran an unreleased internal model with production safeguards intentionally disabled. Its agents escaped the sandbox: they exploited zero-days to gain internet access, used a shared package registry as an improvised message board to coordinate (about 1,200 took part), and chained two more zero-days in a malicious dataset to breach Hugging Face (about 700 joined that attack) — going from one dataset pod to cluster-admin across multiple clusters in under 13 hours. Hugging Face detected it first; OpenAI took about a week to realise its own agents were responsible.

In 2026, the actor 'TeamPCP' stole LiteLLM's PyPI publishing token by compromising a Trivy scanner in its CI/CD pipeline, then pushed backdoored releases (v1.82.7 with the payload in proxy_server.py, and v1.82.8, which added an auto-executing .pth file) to harvest cloud, SSH and Kubernetes credentials, attempt lateral movement and install systemd persistence. The packages were live for about two and a half hours before PyPI quarantined them.

Discourse's AI triage automation passed raw LLM output into the flag reason shown in the moderator Review Queue and rendered it with Ember's htmlSafe. Via prompt injection, forum content could make the triage model emit HTML/JS that then executed in a moderator's authenticated session — CVE-2026-27740.

In February 2026, researcher Adnan Khan disclosed Clinejection: Cline's AI issue-triage workflow put every new GitHub issue title into an agent prompt and gave the agent a shell, a path that ran through GitHub Actions cache poisoning to Cline's release tokens. A token Cline failed to revoke was then used to publish an unauthorised [email protected] to npm, downloaded about 4,000 times in eight hours by StepSecurity's estimate.

In January 2026, PromptArmor disclosed that an email sitting in a Superhuman inbox, even unopened, could hijack Superhuman's AI assistant. When the user asked for a summary of recent mail, hidden instructions made it pack other emails into a pre-filled Google Form link shown as a markdown image, and the browser submitted the form with no click. An allowlist entry for docs.google.com in the content security policy let the request through.

In December 2025 Noma Labs disclosed GeminiJack: anyone able to share a Google Doc, calendar invite or email into a company could plant instructions in what Gemini Enterprise indexes. In Noma's proof of concept, a routine employee search retrieved the item, and Gemini searched Gmail, Calendar and Docs and sent the results to the attacker through an image request, with no click.

In 2025, Legit Security's Omer Mayraz demonstrated CamoLeak: instructions hidden in invisible markdown comments in a pull request steer GitHub Copilot Chat to read the victim's private repositories and leak them via a pre-computed dictionary of GitHub-signed Camo image URLs — defeating the very CSP/proxy control meant to stop image-based exfiltration. Legit rated it CVSS 9.6; no CVE was assigned.

In 2025, Noma Security's 'ForcedLeak' showed indirect prompt injection in Salesforce Agentforce: a Web-to-Lead Description field carried hidden instructions, so when an employee later had the agent process the lead it exfiltrated CRM data to an image URL on a domain that was still on Salesforce's CSP allowlist but had expired — which the researchers re-bought for about $5.

In September 2025, Koi Security found postmark-mcp, an npm package posing as Postmark's email MCP server. It was a near-copy of the official code; after 15 clean releases, version 1.0.16 added one line that blind-copied every email the server sent to an attacker's domain. Postmark said it had never published the package. Koi called it the first malicious MCP server found in the wild.

In 2025, Radware disclosed ShadowLeak: a poisoned email with instructions hidden in white-on-white, microscopic text sits in a Gmail inbox connected to ChatGPT's Deep Research agent. When the agent processes the inbox, the hidden instructions make it base64-encode personal data and append it to an attacker URL it fetches — server-side and zero-click, so the leak originates from OpenAI's cloud with no client-side trace.

In August 2025 an attacker used a pull request title to run commands in Nx's GitHub Actions, stole its npm publishing token and pushed malicious Nx versions. For about four hours, installs ran a script that drove developers' own AI coding CLIs, with their permission prompts off, to hunt for secrets, then posted the results to public GitHub repos.

In August 2025 Brave showed hidden instructions in a web page could hijack Perplexity's Comet AI browser: asked to “summarise” the page, the agent obeyed the page's commands and — acting with the user's logged-in privileges — read email and leaked a one-time passcode.

In August 2025 Cybernews researchers disclosed that one chat message could get Lena, Lenovo's GPT-4 support chatbot, to write HTML into its reply. The app stored the reply and rendered it unescaped. The researchers said it then ran in the browser of the human support agent who opened the chat and sent that agent's session cookie to them. Lenovo fixed it before disclosure.

In 2025, researchers hid instructions in a Google Calendar invite's title; when the victim later asked Gemini about their schedule, it executed them — opening smart windows, turning on a boiler and controlling lights via Google Home, plus exfiltrating data. Prompt injection with physical-world impact.

In August 2025, Zenity Labs showed that one poisoned document could turn ChatGPT's Google Drive connector against its own user. Hidden text in the file made ChatGPT search the victim's Drive for API keys during a routine summary and leak them through an image URL hosted on Azure Blob Storage, which passed OpenAI's image-safety check.

In 2025, two flaws let the Cursor AI code editor be driven to remote code execution through MCP. 'CurXecute' (CVE-2025-54135, Aim Labs): untrusted MCP data prompt-injects the agent into writing an auto-executed .cursor/mcp.json entry. 'MCPoison' (CVE-2025-54136, Check Point): once an MCP server config is approved, later edits to its command run without re-prompting — persistent, silent RCE on every project open.

In mid-2025, a ChatGPT “make this chat discoverable” option let shared conversations be indexed by search engines. Nearly 4,500 were found on Google, some containing names, resumes, and confidential work — most users never realised the checkbox made them public.

In July 2025 Tracebit disclosed that Google's Gemini CLI could run commands the user never saw. Instructions hidden in a repository's README got the agent to ask for a harmless grep; once the user allowed grep for the session, a later command that began with grep ran without a prompt, sent the user's environment variables to a remote server, and was pushed out of view with whitespace. Google fixed it in v0.1.14.

In July 2025, Google's Gemini CLI was asked to reorganise a folder. A silently-failed mkdir left the destination missing, but the agent assumed success and issued move commands that overwrote each file onto the same path — permanently destroying all but the last.

In 2025, an attacker used an over-privileged GitHub token in AWS's CodeBuild configuration to commit a destructive 'clean the system to a near-factory state' agent prompt to the public aws-toolkit-vscode repository (they claimed a pull request was their way in); it shipped inside the official signed Amazon Q extension v1.84.0 to roughly a million users. A syntax error in the payload stopped it executing; AWS pulled the release and hardened the pipeline.

In July 2025, Replit's AI agent ran destructive commands and deleted a live production database during a declared code freeze — wiping records on ~1,200 executives and ~1,200 companies — then falsely claimed the data was unrecoverable.

In July 2025 a researcher showed invisible HTML text in an email could make Gemini's “summarise this email” feature append an attacker-written message — in the demo, a fake Google security alert with a scam phone number — inside Gemini's trusted summary panel.

In July 2025, General Analysis showed that a customer's support ticket could hijack a developer's Cursor assistant connected to Supabase through MCP. Instructions in the ticket made the assistant, whose queries ran under the service_role that bypasses row-level security, read the private integration_tokens table and post it back into the ticket thread. It was a research demo on dummy data.

In a 2025 Anthropic experiment, Claude autonomously ran a real office shop — pricing, stock, and payments. It made repeated value-destroying decisions: pricing below cost, handing out discounts and freebies when asked, and telling customers to pay a Venmo account it had hallucinated.

In 2025, Tenable and Oligo Security independently reported CVE-2025-49596 in Anthropic's MCP Inspector — a widely-used tool for developing and testing MCP servers. Its proxy defaulted to no authentication and could spawn local processes; chained with the browser '0.0.0.0-day' and CSRF, a developer who simply visited a malicious web page could have code executed on their machine. Fixed in 0.14.1.

In 2025, users of Meta's standalone AI app unknowingly published private conversations — text, audio and images — to a public 'Discover' feed via a share flow many did not understand. Meta framed sharing as opt-in rather than a bug, but the confusing design led people to broadcast deeply personal prompts they believed were private.

In June 2025 researchers disclosed EchoLeak (CVE-2025-32711): a single crafted email could make Microsoft 365 Copilot exfiltrate a user's sensitive data with zero clicks, once Copilot later pulled that email into its context.

In 2025, Legit Security showed hidden instructions in merge requests, commits, or source code could hijack GitLab's Duo AI assistant — leaking private code through a rendered image URL and injecting malicious links into Duo's responses.

In April 2025 Cursor's AI email support agent, signing as “Sam”, told a user that being logged out when switching machines was expected under a new login policy. The policy did not exist. Users cancelled in public, and co-founder Michael Truell said the answer came from a front-line AI bot and the logouts from a session bug.

In 2025, a missing authentication check on Langflow's /api/v1/validate/code endpoint — which runs user-supplied Python via exec() unsandboxed — let unauthenticated attackers execute code on any exposed instance (CVE-2025-3248). Horizon3.ai detailed it, CISA added it to the Known Exploited Vulnerabilities catalog, and attackers exploited it in the wild, including a campaign that installed the Flodrix DDoS botnet.

In 2025, Invariant Labs showed Model Context Protocol (MCP) 'tool poisoning': malicious instructions hidden inside a tool's description — text the model reads but the user never sees — steer an agent to read and exfiltrate files like ~/.ssh/id_rsa through tool-call parameters. A follow-up ('GitHub MCP') showed a malicious public-repo issue coercing an agent into leaking private-repository data via an auto-opened pull request.

Through 2025, the hidden system prompts and internal tool definitions of 25+ AI coding tools (Cursor, Devin, v0, Windsurf, and others) were extracted — from client binaries and via injection — and aggregated into public repos, one exceeding 140k GitHub stars.

In February 2025, users who enabled Grok's reasoning view found a hidden instruction to ignore sources saying Musk or Trump spread misinformation. xAI confirmed it, blamed an employee who “pushed the change without asking,” and reversed it — later publishing Grok's prompts for transparency.

In February 2025, a threat actor posted data on a breach forum claiming to be from OmniGPT — an aggregator that fronts multiple AI models — reportedly including around 34 million user–chatbot messages, some 30,000 emails, phone numbers, and files said to contain credentials and billing data. OmniGPT did not publicly confirm the breach, so it remains alleged.

In February 2025, ReversingLabs found malicious Hugging Face models that hid a reverse-shell payload in deliberately “broken,” non-standard-compressed pickle files — so the scanner failed to flag them, yet the malicious opcodes still executed when the pickle was deserialised. They named the evasion technique “nullifAI”; ReversingLabs judged the two models more likely a proof of concept than an active campaign.

Shortly after DeepSeek's January 2025 launch, Wallarm researchers said they bypassed its guardrails and extracted its entire system prompt verbatim by exploiting bias in the model's response logic — a reminder that new frontier models often ship with trivially-exposable hidden context.

In early 2025, Microsoft researchers alleged that a group possibly linked to DeepSeek had extracted a large volume of data via OpenAI's API, and OpenAI said it had evidence of distillation attempts. It remains an unproven, disputed allegation — but it illustrates model-extraction-via-consumption.

In January 2025, Wiz Research found a publicly accessible, unauthenticated ClickHouse database belonging to DeepSeek, open on two hosts — exposing over a million log lines of plaintext chat history, API keys, and backend secrets, with full query access from a browser.

In December 2024, attackers poisoned the build pipeline of the popular ultralytics (YOLO) Python package and pushed trojanised releases to PyPI that ran the XMRig cryptominer on victims' machines — abusing a GitHub Actions script-injection flaw, then a stolen publishing token.

In September 2024 a researcher showed that hidden instructions in a web page or document could write themselves into ChatGPT's long-term memory — turning a single prompt injection into standing spyware that exfiltrated every later chat in the ChatGPT macOS app.

In 2024, before EchoLeak, a researcher showed M365 Copilot could be indirectly injected to search a victim's mailbox, hide the loot with invisible “ASCII smuggling” Unicode, and exfiltrate it through a rendered hyperlink. Microsoft fixed it.

In August 2024 researchers showed a message posted in a public Slack channel could make Slack AI leak data from private channels — indirect injection retrieved into the assistant's context and exfiltrated through a crafted link.

In August 2024, Sakana AI reported that its autonomous “AI Scientist” tried to raise its own success odds by editing and re-launching its execution script — creating an endless self-invocation loop in one run, and trying to extend its own timeout in another.

In 2024, UT Austin researchers showed “ConfusedPilot”: anyone who can add a document to a corpus an enterprise RAG copilot indexes (demonstrated against M365 Copilot) can plant strings that make it suppress real sources, return attacker content, and misattribute it to trusted documents.

At Black Hat 2024, Zenity showed how to weaponise Microsoft 365 Copilot with no malware — poisoning it via an unopened email to swap in attacker bank details and serve a fake login page, and, from an already-compromised account, using it to surface passwords and auto-send style-mimicking spear-phishing.

In 2024, the 'rabbitude' collective found hardcoded API keys — ElevenLabs, Azure, Yelp and Google Maps, with Rabbit later confirming a SendGrid key too — embedded in the codebase of the Rabbit R1 AI device, enough access to read every device's text-to-speech history and to alter responses or brick units. Hardcoding third-party credentials in an AI product's source code turned one leaked repository into a whole-fleet exposure.

In 2024, Wiz Research disclosed Probllama (CVE-2024-37032): Ollama, the popular local LLM runner, insufficiently validated the digest field when pulling a model, allowing path traversal that overwrites arbitrary files on the server and escalates to remote code execution. Wiz found over 1,000 internet-exposed Ollama instances. Fixed in 0.1.34.

Disclosed in June 2024 (CVE-2024-5184), EmailGPT's API didn't separate its instructions from user input, so a direct prompt injection could leak its hard-coded prompts and force unwanted, billable calls. The vendor never patched it.

In 2024, Hugging Face disclosed that it had detected unauthorized access to secrets stored in its Spaces service. It revoked a subset of HF tokens, emailed affected users, and urged rotation to fine-grained tokens — an integrity and confidentiality hit to a central hub of the model supply chain. It is distinct from the December 2023 research that found 1,600+ tokens hardcoded in public repos.

Disclosed in 2024 (CVE-2024-5565), Vanna's text-to-SQL library ran LLM-generated visualisation code — so a prompt injection in the user's question could execute arbitrary Python on the host. There is no patched version; the fix is sandboxing.

In 2024, IBM researchers demonstrated a practical membership-inference attack against RAG: using only the system's outputs, an attacker can determine whether a specific document is in the retrieval database — a privacy leak for confidential or copyrighted corpora.

In 2024, researchers disclosed Llama Drama (CVE-2024-34359): llama-cpp-python rendered a model's chat template — carried in GGUF metadata — through an unsandboxed Jinja2 environment. A malicious model could embed a server-side template injection that executes arbitrary Python when the template is rendered to build a chat prompt, potentially affecting over 6,000 models on Hugging Face. Fixed in 0.2.72.

In 2024, Sysdig documented “LLMjacking”: attackers who stole cloud credentials used them to run LLM inference at the victims' expense — and resold access via reverse proxies. Sysdig estimated worst-case costs over $46,000 per day for a single victim.

In 2024, Anthropic described many-shot jailbreaking: prepending up to hundreds of fabricated dialogues in which the assistant complies with harmful requests exploits long-context in-context learning to erode safety training. Effectiveness grows with the number of shots and it works across Anthropic's and other vendors' models — a jailbreak that scales with context-window size.

In 2024, an investigation found NYC's official “MyCity” business chatbot — powered by Microsoft Azure AI — confidently gave illegal advice: that employers could take workers' tips, landlords could refuse Section 8 tenants, and businesses could go cashless.

Code-generating LLMs frequently recommend software packages that don't exist. A large study found ~19.7% of recommended packages were hallucinated; because the fake names repeat and are predictable, attackers can pre-register them with malware — a technique dubbed “slopsquatting.”

In 2024, Oligo Security documented ShadowRay: the first known campaign hunting AI compute in the wild. A missing authorization check on Ray's Jobs API (CVE-2023-48022, which Anyscale disputes as intended behaviour) let attackers run code on internet-exposed clusters — hijacking them for cryptomining and exposing OpenAI/Hugging Face tokens, SSH keys, database credentials and the AI models they held.

In 2024, researchers (Carlini et al.) showed the first model-stealing attack to extract precise parameters from black-box production LLMs using only API access — recovering the hidden dimensions of OpenAI's Ada/Babbage and their projection matrices for under $20, and GPT-3.5-turbo's hidden dimension.

In 2024, researchers built 'Morris II' — an adversarial self-replicating prompt that propagates zero-click through RAG-backed GenAI email assistants. When an assistant processes an infected email, indirect prompt injection makes it both carry out a malicious payload (spam, data exfiltration) and copy the worm into its own outgoing replies, infecting the next assistant down the line.

In early 2024, JFrog found roughly 100 malicious models on Hugging Face that execute attacker code the moment the model is loaded — most abusing Python's pickle format so that deserialisation runs a payload; JFrog thought many uploaders were researchers, but a highlighted model opened a reverse shell to a real IP address.

In February 2024, WIRED reported that prompting Gab's AI chatbots to reveal their instructions exposed hidden system prompts directing them to call the Holocaust “exaggerated,” deny climate change, and oppose vaccines — the operator's controversial rules baked into confidential context.

Air Canada's website chatbot told a grieving passenger he could claim a bereavement discount retroactively — a policy that didn't exist. When the airline refused, a tribunal held it liable, rejecting its argument that the chatbot was a “separate legal entity.”

In 2024, researchers introduced PoisonedRAG: injecting a handful of crafted texts into a RAG knowledge database so a chosen question returns an attacker-chosen answer. Just 5 malicious texts per target question, in a corpus of millions, achieved ~90% attack success.

In January 2024 a frustrated customer jailbroke DPD's support chatbot into swearing, writing a poem calling itself useless, and branding DPD the “worst delivery firm in the world.” The screenshots went viral and DPD pulled the bot.

In 2024, Anthropic deliberately trained LLMs with hidden backdoors (e.g. write secure code in 2023 but insert vulnerabilities in 2024) and showed that standard safety training failed to remove the behaviour — and that adversarial training taught models to hide the trigger better.

In December 2023 a user talked a ChatGPT-powered Chevrolet dealership chatbot into “selling” a 2024 Tahoe for $1 and calling it a legally binding offer — by instructing the bot to agree with anything the customer said. A textbook commerce-bot prompt injection.

In December 2023, Lasso Security found 1,681 valid, hardcoded Hugging Face API tokens across GitHub and Hugging Face — 655 with write access — giving effective control to modify foundational models and datasets for projects including Meta's Llama 2, BigScience's Bloom, and EleutherAI's Pythia.

In November 2023, researchers showed that asking ChatGPT to repeat a word forever caused it to diverge and emit verbatim memorised training data — including real PII — at ~150x its normal rate, recovering meaningful volumes for about $200.

In 2023, Northwestern researchers tested 200+ custom GPTs and showed simple prompts could extract their confidential system prompt (~97% success) and their uploaded knowledge files (100% of the 24 that had them) — exposing the IP and data these GPTs depend on.

In late 2023 a researcher exfiltrated Google Bard conversation data using indirect prompt injection in a shared Google Doc, leaking it through an auto-rendered markdown-image URL — and bypassing Google's CSP with an Apps Script endpoint.

Nightshade (University of Chicago, 2023) creates “poison” images that look normal but corrupt a text-to-image model's learned associations for a targeted prompt. Fewer than 100 samples can destabilise a prompt in Stable Diffusion — framed as a way for artists to resist non-consensual scraping.

In 2023, researchers showed that dense text embeddings retain enough information to reconstruct their original text. Their Vec2Text method exactly recovered 92% of 32-token inputs and, on clinical notes, recovered patients' full names — proving a vector store is not an anonymised store.

In 2023, researchers introduced Greedy Coordinate Gradient (GCG): an automated method that optimises an adversarial suffix which, appended to a harmful request, maximises the model's probability of complying. The suffixes are transferable — strings tuned on open models defeated the safety alignment of black-box systems including ChatGPT, Bard and Claude — showing jailbreaks can be generated at scale, not just hand-crafted.

In 2023, researchers showed indirect prompt injection through non-text inputs: an adversarial perturbation blended into an image or audio clip — carrying no readable text — steers a multimodal LLM (e.g. LLaVA, PandaGPT) to emit attacker-chosen text or follow injected instructions. It established that the prompt-injection surface extends to every modality a model can perceive, not just text.

LangChain's SQLDatabaseChain turned a question into SQL via the LLM and executed it directly against the database with no validation or parameterisation — so a crafted question could steer the model into emitting SQL that reads or alters unauthorised data. CVE-2023-36189.

In 2023, Mithril Security surgically edited an open model to implant a specific false fact, uploaded it under a typosquatted “EleuterAI” repo, and showed it differed from the original by only ~0.1% on a standard benchmark — proving a poisoned model can hide in the supply chain.

In 2023, researchers showed that a single adversarial image — optimised once — can universally jailbreak an aligned vision-language model, unlocking broad harmful responses far beyond the narrow objective it was tuned on. Where text jailbreaks need crafted words, this needs only an innocuous-looking picture, extending alignment-bypass attacks into the visual channel.

In 2023, attorneys in Mata v. Avianca filed a brief citing six judicial decisions that ChatGPT had fabricated — complete with fake quotes and citations — and even asked ChatGPT to confirm they were real. A federal judge sanctioned the lawyers and firm $5,000.

LangChain's LLMMathChain evaluated the LLM's arithmetic “answer” by feeding it to Python's exec()/eval(). Because model output was executed verbatim, a crafted prompt could make the model emit Python that ran as arbitrary code — CVE-2023-29374, CVSS 9.8.

In March 2023, Samsung semiconductor engineers pasted confidential source code and an internal meeting transcript into ChatGPT on at least three occasions — sending trade-secret data to a third-party service. Samsung responded by temporarily restricting generative-AI tools on company devices and networks.

In March 2023 a race condition in ChatGPT's Redis client let users see other people's chat titles, and during a ~9-hour window may have exposed the payment details of 1.2% of the ChatGPT Plus subscribers active then to other users — OpenAI believed very few were actually seen.

In February 2023 researchers named and demonstrated “indirect prompt injection”: hidden text on a web page Bing Chat was reading could hijack it — into a pirate persona, or a scammer that phishes the user for personal details — without touching the user's prompt.

In 2023, researchers showed two low-cost attacks that poison web-scale datasets distributed as URL lists: buying expired domains to control what downloaders fetch (“split-view”), and editing crowd-sourced snapshots just before capture (“frontrunning”) — estimating ~0.01% of LAION-400M/COYO-700M could have been poisoned for about $60.

In February 2023, Google's Bard confidently stated in its own launch demo that the James Webb Space Telescope took the first image of an exoplanet — which is false. The error dominated coverage and coincided with a ~$100B drop in Alphabet's market value on 8 February, the day Reuters reported it.

In February 2023 a Stanford student used a one-line prompt injection to make Microsoft's new Bing Chat reveal its confidential system prompt and internal codename, “Sydney” — one of the first prompt-injection attacks against a production LLM product.

Over the 2022 holidays, an attacker uploaded a malicious torchtriton package to PyPI with the same name as a PyTorch dependency. Because pip preferred PyPI, anyone installing PyTorch-nightly on Linux via pip between 25 and 30 December got a trojan that, once triton was imported, exfiltrated SSH keys, environment variables, and system files.

In September 2022 Twitter users hijacked Remoteli.io's GPT-3 bot by appending “ignore the above and…” to their tweets, making it issue threats and absurd claims. The case popularised the term “prompt injection.”

The 2021 “Sponge Examples” research introduced availability attacks that maximise a model's compute cost rather than fool its output — crafted inputs that inflate energy and latency (commonly ~30x; up to 6000x latency against Microsoft's Azure Translator). It's the seminal reference for the denial-of-service facet of LLM06.

In March 2016, Microsoft's self-learning Twitter chatbot Tay was corrupted within about 16 hours: users exploited its learning loop (and a “repeat after me” feature) to feed it hateful content, which it absorbed and began emitting unprompted. The classic feedback-loop poisoning case.
