Description
MacCMS v10 through 2026.1000.4056 contains a mass assignment vulnerability in index/Comment::saveData() that allows unauthenticated attackers to set arbitrary mac_comment columns including user_id. Attackers can submit anonymous comments with a crafted user_id parameter to attribute them to any registered member, displaying that member's avatar and impersonating them.
