Doc Text:
A flaw was found in PHP due to inadequate validation of user-supplied XML input. By leveraging specially crafted XML code, a remote attacker could obtain sensitive information by viewing the contents of arbitrary files on the system or initiating requests to external systems. This issue may allow unauthorized access to sensitive data and the potential for network scanning of internal and external infrastructure.
