Vulnerability Title
Runtipi unauthenticated /api/auth/reset-password allows operator account takeover during active reset window
Source: CVE Program / CVE List V5
Vulnerability Description
Runtipi is a personal homeserver orchestrator. Prior to 4.8.0, an unauthenticated attacker can reset the operator (admin) password when a password-reset request is active, resulting in full account takeover. The endpoint POST /api/auth/reset-password is exposed without authentication/authorization checks. During the 15-minute reset window, any remote user can set a new operator password and log in as admin. This vulnerability is fixed in 4.8.0.
