A user with read access to a repository could place a commit of their own in it, through a fork pull request or an AGit push, and submit a review naming that commit on a pull request whose head branch is in the same repository. On instances with a runner serving the repository, the attacker's workflow then ran without approval, received the Actions secrets of the repository and its owner, and got a `GITEA_TOKEN` with write access to the repository. Review-triggered workflows now run on the pull request head.\n\n## Affected\n\n- `gitea.dev >= 1.19.0 < 28.3.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
