What is CVE-2026-102603?

The Gotify server, a platform for real-time messaging via WebSocket, has a security flaw in its password change mechanism. Before version 3.0.0, the system allowed changing a user's password without requiring verification of the current password or an elevated authentication step. An attacker with access to a valid client token could exploit this flaw to reset passwords, leading to unauthorized access and potential account takeovers. This issue was addressed in version 3.0.0, underscoring the importance of proper authentication protocols to safeguard user accounts.
