Executive Summary

This vulnerability affects Gitea versions up to 1.26.4 where public-only API tokens do not enforce restrictions properly on team API routes. The issue occurs because the /api/v1/teams/{id} routes fail to validate organization visibility when using public-only tokens, allowing access to private team repositories and activity feeds.

Detection Guidance

Check Gitea version with: curl -s http://localhost:3000/api/v1/version | grep version. If version <= 1.26.4, the system is vulnerable. Review API logs for unauthorized access attempts to /api/v1/teams/{id} routes.

Impact Analysis

This flaw enables unauthorized access to sensitive information, though it requires a valid public-only token scoped to a private organization. Attackers could view private team repositories and activity feeds, compromising confidentiality of private data.

Mitigation Strategies

Upgrade Gitea to version 1.27.0 or later immediately. Review and revoke any public-only tokens scoped to private organizations. Monitor team API routes for unusual access patterns.
