Description
Fat Free CRM before 0.26.0 contains an insecure direct object reference vulnerability that allows authenticated users to modify or delete other users' comments because CommentsController#update and #destroy use an unscoped Comment.find without authorization checks. Attackers can send PUT or DELETE requests to /comments/:id with enumerable sequential IDs to edit or delete comments on contacts, accounts, leads, and opportunities owned by others.
