Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the processing of url-pattern rules when both @ServletSecurity annotations and web.xml defined security-constraint are present on the same url-pattern, and the web.xml contains more than one url-pattern for a servlet with a security-constraint applying to only some of those definitions. An attacker can bypass intended security restrictions by targeting url-pattern definitions that are not properly constrained.
