Poisoning GitHub's Runner Images Supply Chain Attack
A critical vulnerability in GitHub's actions/runner-images repository allowed arbitrary code execution on self-hosted runners, potentially enabling modification of GitHub's runner base images.

The researcher gained persistence, accessed secrets, and could have inserted malicious code into GitHub's runner images used by customers.
