CVE-2026-31881 Details
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.
A vulnerability in Runtipi versions prior to 4.8.0 allows an unauthenticated attacker to take over the admin account by resetting the operator password during an active password-reset request. The vulnerability arises because the POST /api/auth/reset-password endpoint lacks authentication and authorization checks. When a password-reset request is active, any remote user can exploit this flaw to change the operator password and gain admin access.
Users should update to Runtipi version 4.8.0 or later, where this vulnerability has been fixed.
