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
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.
