CVE-2026-102603
Medium
Description
Gotify server is a simple server for sending and receiving messages in real-time per WebSocket. Prior to 3.0.0, the password change endpoint (POST /current/user/password) accepts a valid client token without requiring the account's current password or another elevated authentication step. An attacker who obtains a client token can set a new password for the associated user, taking control of password authentication and forcing account recovery through an administrator or direct database access. This issue is fixed in version 3.0.0.
