FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, the load_customer_info action in POST /conversation/ajax returns complete customer profile data to any authenticated user without verifying mailbox access. An attacker only needs a valid email address to retrieve all customer PII. Version 1.8.213 fixes the issue.
