Vulnerability Description
lamp-cloud through 5.10.0 contains an authorization bypass vulnerability in FileAnyoneController that allows authenticated users to download arbitrary attachments. Attackers can retrieve other users' stored files by supplying valid attachment identifiers to the /anyone/file/down and /anyone/file/download endpoints, as the application never validates file ownership against the created_by column.
