Vulnerability Title
Semaphore UI: CSRF vulnerability on password change endpoint - No CSRF token or password confirmation
Source: CVE Program / CVE List V5
Vulnerability 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.
