Authenticated file read and overwrite via hook traversal
Published Feb 6, 2026 · Updated Feb 6, 2026
Path traversal in Gogs 0.13.3 and earlier allows remote authenticated users to read or overwrite server files through Git hook editing. The Git hook edit handlers pass the URL-decoded name route parameter to git.Repository.Hook, which joins it under custom_hooks without validation. Repository Admin or higher access plus AllowGitHook is required, and access remains limited by the Gogs process permissions.
