Description

OWASP BLT is a QA testing and vulnerability disclosure platform that encompasses websites, apps, git repositories, and more. Prior to 2.1.2, .github/workflows/pre-commit-fix.yaml uses pull_request_target (privileged trigger) but checks out and executes code directly from the attacker's fork, enabling RCE with write permissions. This vulnerability is fixed in 2.1.2.
