Technical details

An insecure direct object reference exists in the FileAnyoneController's findUrlById endpoint, which accepts a list of file IDs and returns signed storage URLs without verifying the requester owns those files. An authenticated user can supply arbitrary file IDs belonging to other users to obtain valid access URLs. The vulnerability requires authentication but performs no ownership or tenant checks before generating URLs.
