DescriptionCVE.org

Gitea's stopwatch API does not re-validate repository access permissions. After a user's access to a private repository is revoked, they may still view issue titles and repository names through previously started stopwatches.

An authenticated attacker with prior access to a private repository can enumerate issue titles and repository names even after their permissions have been removed. A patch is available to enforce proper access control validation.
