Description
Semaphore UI is a web interface for managing DevOps tools. Prior to 2.18.21, the /api/users/{id}/password endpoint accepts a cross-site request using the authenticated user-s semaphore session cookie without CSRF protection or current-password confirmation, allowing an unauthenticated attacker to change an administrator-s or another user-s password after user interaction. This issue is fixed in version 2.18.21.
