Repository compromise via token-bearing workflow artifact
Published Apr 18, 2025 · Updated Apr 21, 2025
Sensitive-information exposure in Udo Munk z80pack 1.38 and earlier allows remote attackers to obtain a workflow's GITHUB_TOKEN. The makefile-ubuntu.yml workflow archives the working directory for z80pack-ubuntu, thereby packaging .git/config and its automatically inserted token in a downloadable artifact. Exploitation requires monitoring a workflow run and winning the brief interval before completion, after which the token permits malicious commits or rewritten release tags.
