Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-863.
Summary
Gitea versions from 0 through 1.27.3 base fork pull request approval on the user who triggers an event, not the pull request author (CWE-863). When a maintainer triggers a pull_request event, such as adding a label, the run skips approval but still uses the fork's workflow. Fork-controlled workflow code can then run on the base repository's runners without approval. A public exploit is linked in the references.

Description from the CNA
Gitea Actions decided whether a fork pull request run needed approval based on the user who triggered the event rather than the pull request author. For `pull_request` activity triggered by a maintainer during ordinary triage, such as adding a label, the run was created without requiring approval, while the workflow definition was still taken from the fork head. Where Actions is enabled and a matching runner is registered, fork-controlled workflow code could run on the base repository's runners without an explicit approval.
