What it is

KTM System e-BOK allows the session identifier to be set by the client prior to authentication. If a cookie with a valid name is set, its value remains unchanged after successful login. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session.

This issue was fixed in the patch published in June 2026.
