Summary

Hide ▲

Google's ADK Python repository workflows had a prompt-injection flaw that let a public GitHub issue steer a trusted triage bot into a privileged code-fixing path. Researchers showed the chain could reach the CI runner, execute arbitrary code, and expose the bot PAT and cloud credentials. Google removed issue-analyze.yml, issue-fix.yml, and pr-analyze.yml after the proof of concept; the record does not show in-the-wild exploitation.
