Executive Summary

CVE-2026-24791 is a vulnerability in Gitea where public-only tokens can bypass restrictions and access private resources through self routes under /api/v1/user. Public-only tokens should only access public data but can retrieve or modify private information like SSH keys, emails, or repositories due to insufficient enforcement.

Detection Guidance

To detect this vulnerability, check if your Gitea instance is running a vulnerable version (1.22.3 through 1.26.1). Run 'gitea --version' to verify the version. Inspect API logs for unauthorized access attempts to /api/v1/user endpoints with public-only tokens.

Impact Analysis

This vulnerability allows unauthorized access to private data such as SSH keys, email addresses, OAuth applications, Actions secrets, and repositories. Attackers could exploit leaked tokens to add credentials, modify settings, or enumerate private repositories, potentially leading to data breaches or account compromise.

Mitigation Strategies

Upgrade Gitea to version 1.26.2 or later immediately. This version includes fixes for permission-related issues and token scope enforcement. Gitea Cloud instances will auto-upgrade during maintenance.
