🛡️ Sentinel: Security Fix - Command Injection
🚨 Severity: HIGH
💡 Vulnerability: Direct expansion of untrusted GitHub context variables (
github.head_ref,github.event.pull_request.body,github.event.pull_request.user.login) inrunsteps.🎯 Impact: Malicious actors could craft pull requests with specially formatted bodies or branch names to execute arbitrary commands within the GitHub Actions runner environment.
🔧 Fix: Properly mapped untrusted context variables to environment variables before using them in shell scripts.
✅ Verification: Verified YAML syntax validity with
check_workflows.py.Documentation of this pattern has been added to
.Jules/sentinel.md.PR created automatically by Jules for task 7434107955981527810 started by @christopherfoxjr
