AI-suggested
Upgrade Gitea to version 28.3.0 or later, where this vulnerability is fixed. The fix ensures system users own no repositories and restricts API routes to prevent unauthorized repository enumeration. No additional mitigation is required once the system is updated.
Description
Gitea versions prior to 28.3.0 contain a vulnerability where Actions task tokens authenticate as a shared system user with no owner restrictions, allowing users who can run workflows to list all repositories on the instance, including private ones, via the REST API. Repository contents remain protected by permission checks. The issue is fixed in version 28.3.0 by ensuring system users own no repositories and restricting API routes accordingly.
