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.

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.
