Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-862.

Summary

Gitea lists the pull requests that reference an issue on a repository or organization project board without checking whether the viewer can read them. When a private pull request mentions an issue on a board the viewer can open, the board reveals the private repository's path and the pull request's number, title and state, and anonymous visitors can see this on a public board. The pull request body, diff and files are not exposed. The weakness is CWE-862, Missing Authorization, and CVSS 3.1 scores it 7.5 (HIGH).

Description from the CNA

Repository and organization project boards listed the pull requests that reference each issue on the board without checking whether the viewer can read them. When a private pull request mentions an issue on a board the viewer can open, the board revealed the private repository's path and the pull request's number, title and state, to anonymous visitors in the case of a public board. The pull request body, diff and files were not exposed. Boards now skip linked pull requests in repositories where the viewer cannot read pull requests.
