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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
