What is CVE-2016-8738?

In versions of Apache Struts from 2.5 to 2.5.5, an application susceptible to this vulnerability may expose itself to a denial of service attack through improper handling of URL input. If an application utilizes the built-in URLValidator without adequate checks, an attacker could craft a malicious URL that, when validated, could cause the server to become unresponsive. This poses significant risks to web application integrity and availability, thereby necessitating prompt remediation.
