Summary
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, the assigned-only restriction is applied to direct conversation view and folder queries, but not to non-folder query builders. Global search and the AJAX filter path still reveal conversations that should be hidden. Version 1.8.215 fixes the vulnerability.
