A brand new class of immediate injection vulnerabilities, dubbed “PromptPwnd,” has been uncovered by cybersecurity agency Aikido Safety.
The issues have an effect on GitHub Actions and GitLab CI/CD pipelines which might be built-in with AI brokers, together with Google’s Gemini CLI, Claude Code, and OpenAI Codex. The vulnerability has been confirmed to impression not less than 5 Fortune 500 firms, with proof suggesting the difficulty is widespread.
Aikido Safety, which first recognized and disclosed this vulnerability sample, has open-sourced Opengrep guidelines to assist safety distributors detect the flaw.
The vulnerability sample includes untrusted consumer enter being injected into AI prompts, permitting the AI agent to execute privileged instructions, which might result in the leakage of secrets and techniques or manipulation of workflows. This marks the primary confirmed real-world demonstration of AI immediate injection efficiently compromising CI/CD pipelines.
Immediate Injection Flaw in GitHub Actions
The assault leverages the growing integration of AI into software program growth workflows for duties like computerized situation triage and pull request labeling.
The vulnerability arises when untrusted content material from sources like GitHub situation titles or our bodies is instantly fed into AI prompts. An attacker can embed malicious directions inside this content material.
GitHub Workflows Vulnerability
The AI mannequin then misinterprets these directions as instructions, not knowledge, and makes use of its built-in instruments to carry out unauthorized actions. This could embrace modifying pull requests or, in additional extreme circumstances, exfiltrating delicate credentials and API keys.
A chief instance of this vulnerability was present in Google’s personal Gemini CLI repository. The workflow handed untrusted consumer enter from GitHub points instantly into the mannequin immediate.
Aikido Safety created a proof-of-concept by submitting a malicious situation with hidden directions. The AI agent interpreted these directions and executed a command to edit the difficulty, embedding delicate API keys and tokens instantly into the difficulty physique, thereby exposing them. Following Aikido’s accountable disclosure, Google patched the vulnerability inside 4 days.
This vulnerability will not be remoted to a single AI agent. Researchers discovered that related architectural patterns exist throughout many AI-powered GitHub Actions, together with Claude Code Actions and OpenAI Codex Actions, particularly when safety settings are misconfigured to permit non-privileged customers to set off workflows.
To handle the “PromptPwnd” vulnerability, Aikido Safety recommends a number of remediation steps. Organizations ought to limit the toolset out there to AI brokers, avoiding instruments that may write to points or pull requests.
Additionally it is essential to keep away from injecting untrusted consumer enter into AI prompts, or to sanitize and totally validate it if unavoidable. Moreover, all output generated by AI ought to be handled as untrusted code and never executed with out validation.
Limiting the entry of GitHub tokens by IP tackle also can assist limit the potential injury from leaked credentials. Aikido affords a free software to scan GitHub and GitLab repositories for this vulnerability, and builders also can use open-source instruments to verify their .yml information.
