CVE-2026-111673

IceCMS through 4.1.5 contains a missing authentication vulnerability that allows unauthenticated attackers to modify, delete, or disable any account because /User/** is excluded from the Shiro jwt filter. Attackers can send PUT requests to /User/updateUser to set a new password and role on any userId, including administrators, enabling full account takeover.
