CVE-2026-41190
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, when `APP_SHOW_ONLY_ASSIGNED_CONVERSATIONS` is enabled, direct conversation view correctly blocks users who are neither the assignee nor the creator. The `save_draft` AJAX path is weaker. A direct POST can create a draft inside a conversation that is hidden in the UI. Version 1.8.215 fixes the vulnerability.
