The attack involves unsanitized HTTP parameters being output in a form page, allowing attackers to leak cookies and other sensitive information from ca/uhn/fhir/to/BaseController.java via a specially crafted URL. (This module is not generally used in production systems so the attack surface is expected to be low, but affected systems are recommended to upgrade immediately.)
