CVE-2026-41192

Summary

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, the reply and draft flows trust client-supplied encrypted attachment IDs. Any IDs present in attachments_all[] but omitted from retained lists are decrypted and passed directly to Attachment::deleteByIds(). Because load_attachments returns encrypted IDs for attachments on a visible conversation, a mailbox peer can replay those IDs through save_draft and delete the original attachment row and file. Version 1.8.215 fixes the vulnerability.
