What is CVE-2025-58163?

FreeScout, a help desk application built on the PHP Laravel framework, contains a vulnerability that allows authenticated attackers to exploit deserialization of data, resulting in the potential for remote code execution. This issue is present in versions 1.8.185 and below, where specific parameters in the endpoint /help/{mailbox_id}/auth/{customer_id}/{hash}/{timestamp} are not properly validated during their decryption process in app/Helper.php. The lack of thorough sanitization when deserializing the decrypted payload exposes the application to significant security risks. A fix for this vulnerability is included in version 1.8.186.
