CVE-2026-25120 Gogs Allows Cross-Repository Comment Deletion via DeleteComment

What is CVE-2026-25120?

CVE-2026-25120 is a medium-severity missing authorization vulnerability in gogs, published on 19 Feb 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

Gogs is an open source self-hosted Git service. In versions 0.13.4 and below, the DeleteComment API does not verify that the comment belongs to the repository specified in the URL. This allows a repository administrator to delete comments from any other repository by supplying arbitrary comment IDs, bypassing authorization controls. The DeleteComment function retrieves a comment by ID without verifying repository ownership and the Database function DeleteCommentByID performs no repository validation. This issue has been fixed in version 0.14.0.
