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.
Gitea does not properly verify authorization when canceling scheduled auto-merges via the web interface. A user with read access to pull requests may be able to cancel auto-merges scheduled by other users.
Gitea may send release notification emails for private repositories to users whose access has been revoked. When a repository is changed from public to private, users who previously watched the repository may continue to receive release notifications, potentially disclosing release titles, tags, and content.
