Short explanation

Gitea did not reject personal access tokens restricted to public resources on the organization Actions runner registration-token endpoint, allowing restricted tokens to access private repository job data, secrets, and variables.

Why does it matter?

This vulnerability widens the reach of restricted tokens, enabling attackers to register runners that receive jobs, workflow content, and secrets from private organization repositories.

What should be done?

  • Update Gitea following the vendor advisory and release notes
  • Review official patch references and pull requests
  • Audit token scopes and organization permissions

Show the technical text from the sources

Gitea did not reject personal access tokens restricted to public resources (`public-only`) on the organization Actions runner registration-token endpoint, and the runner registered with the resulting token was not limited to public repositories. Holding only such a token with `write:organization` that belongs to an owner of a public organization, an attacker could register an organization-level runner and receive jobs of the organization's private repositories that have Actions enabled, including the workflow content, Actions secrets and variables, and a task token with access to the private repository. The issue widens what the restricted token can reach; it gives nothing beyond what the owner's full account can already do.
