Summary
lamp-cloud through 5.10.1 contains an insecure direct object reference that lets authenticated users obtain storage URLs for other users' files. The findUrlById handler of FileAnyoneController never checks file ownership, so supplying arbitrary file ids returns access URLs. An attacker with a low-privilege account can read uploaded attachments belonging to other users (CWE-639). A proof-of-concept exploit is linked in the references.
