Gitea does not properly validate project ownership in organization project operations. A user with project write access in one organization may be able to modify projects belonging to a different organization.

Gitea does not properly verify repository context when deleting attachments. A user who previously uploaded an attachment to a repository may be able to delete it after losing access to that repository by making the request through a different repository they can access.

Gitea may send release notification emails for private repositories to users whose access has been revoked.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.

NOTE: The vendor has indicated this is not a vulnerability and states "This is a functionality of the software that is limited to a very limited subset of accounts. If you give someone the privilege to execute arbitrary code on your server, they can execute arbitrary code on your server.
