Summary

Fat Free CRM before 0.26.0 contains an insecure direct object reference that lets authenticated users modify or delete other users' comments. CommentsController#update and #destroy look up comments with an unscoped Comment.find and skip authorization checks, so attackers can send PUT or DELETE requests to /comments/:id with sequential IDs to change comments on contacts, accounts, leads, and opportunities owned by others. The CWE is CWE-639.
