Intelligence Summary
GitHub is updating the official actions/checkout GitHub Action to block common Pwn request patterns. The change targets a known risk involving pull_request_target, where workflows can run with elevated privileges. Attackers may try to exploit how untrusted changes are processed when pull_request_target is used. With this update, checkout behavior is hardened to reduce the chance of malicious code execution. Users should update to the recommended actions/checkout version and review workflows using pull_request_target. Teams should verify their CI/CD pipelines to ensure they remain secure after the action update.
