CVE-2026-116474: The `GITEA_TOKEN` of a Gitea Actions job authenticates as the `gitea-actions` system user, and the `/api/v1/user` email and GPG key endpoints accepted that user

The `GITEA_TOKEN` of a Gitea Actions job authenticates as the `gitea-actions` system user, and the `/api/v1/user` email and GPG key endpoints accepted that user

The `GITEA_TOKEN` of a Gitea Actions job authenticates as the `gitea-actions` system user, and the `/api/v1/user` email and GPG key endpoints accepted that user, so a job could register an email address and a GPG key on it; without required email confirmation (the default) the address is stored as activated. Commit verification treats a key without a real owner as the instance signing key, so any user who can run a workflow job could make commits signed with their own key show as trusted and signed by the instance in every repository where they appear, including pull requests to repositories the user cannot write to. The impact is limited to the displayed signature status: enforcement such as required signed commits only checks that a signature is verified and is unaffected, and no access is gained. The `/api/v1/user` routes now reject system users.

What it means for a small business

If your business uses Gitea, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.14%, higher than 3% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored November 1, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
