CVE-2026-24690Network attack vectorHinoki check available

Unauthorized pull-request branch modification via flawed permission checks

Published Jul 3, 2026 · Updated Jul 3, 2026

Improper access control in Gitea before 1.25.5 allows remote attackers to update or rebase pull request branches without authorization. When maintainer edits were enabled, IsUserAllowedToUpdate accepted a maintainer's base-branch merge permission without requiring the pull-request poster's push or force-push permission on the head branch. Reachability requires a pull request permitting maintainer edits and an update or rebase action; exploitation changes head-branch code without disclosing data or interrupting the service.
