CVE-2026-41191
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, "MailboxesController::updateSave()" persists "chat_start_new" outside the allowed-field filter. A user with only the mailbox "sig" permission sees only the signature field in the UI, but can still change the hidden mailbox-wide chat setting via direct POST. Version 1.8.215 fixes the vulnerability.
