CVE-2026-41189

HIGH7.1

FreeScout has assigned-only visibility bypass that allows editing hidden customer-authored threads

Published Apr 21, 2026

Modified 2 days ago

Details

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.
