Official description

KTM System e-BOK is vulnerable to Cross‑Site Request Forgery (CSRF) in both the email-change and password-change functionalities. An attacker can craft a malicious website that, when visited by an authenticated user, automatically sends a forged POST request to the application. This allows the attacker to trigger an unauthorized email or password change on behalf of the victim without their knowledge or interaction. This issue was fixed in the patch published in June 2026.
