Executive Summary

This vulnerability in Gitea occurs because the system does not properly verify the repository context when deleting attachments. As a result, a user who previously uploaded an attachment to one repository may still be able to delete that attachment even after losing access to that repository, by making the deletion request through a different repository they currently have access to.

Impact Analysis

This vulnerability can allow unauthorized deletion of attachments from repositories. Users who should no longer have access to certain repository content might still be able to delete attachments, potentially leading to data loss or disruption of repository integrity.
