CVE-2026-58437Public exploitNetwork attack vector

Private repository exposure via unrestricted push options

Published Aug 13, 2026 · Updated Aug 13, 2026

Improper access control in Gitea 1.26.4 and earlier allows remote authenticated users to expose private repositories via Git push options. HookPostReceive() accepts repo.private and repo.template for existing repositories and writes the flags with UpdateRepositoryColsNoAutoTime instead of restricting them to push-to-create. Owner or repository-admin access and push permission are required; a private repository can become publicly cloneable without an activity entry, webhook, or updated timestamp.
