CVE-2026-41189
Published:April 21, 2026
Updated:May 18, 2026
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, customer-thread editing is authorized through "ThreadPolicy::edit()", which checks mailbox access but does not apply the assigned-only restriction from "ConversationPolicy". A user who cannot view a conversation can still load and edit customer-authored threads inside it. Version 1.8.215 fixes the vulnerability.
