    "title": "Gokapi: Privilege escalation via incomplete API-key permission revocation on user rank demotion",
    "summary": "Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. Prior to version 2.2.3, a privilege escalation vulnerability in the user rank demotion logic allows a demoted user's existing API keys to retain ApiPermManageFileRequests and ApiPermManageLogs permissions, enabling continued access to upload-request management and log viewing endpoints after the user has been stripped of all privileges. This issue has been patched in version 2.2.3.",
