Detailsinfo

A vulnerability has been found in go-gitea Gitea up to 28.0.0 and classified as problematic. This vulnerability affects an unknown functionality of the file /tags/delete of the component Tag. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect integrity, and availability. CVE summarizes:

The Gitea web route for deleting tags (`POST /{owner}/{repo}/tags/delete`) requires only write access to the Code unit, but shares its handler with release deletion and did not check that the target was a plain tag. A collaborator with Code write access and without Releases write access could permanently delete published releases of that repository, including their attachments. Protected tag rules covering the release tag still blocked the deletion.

The advisory is available at github.com. This vulnerability was named CVE-2026-105267 since 10/05/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/07/2026).
