Description

Pig-mesh Pig versions 3.8.2 and below contain a remote code execution vulnerability in the Quartz management function of the system management module. This flaw allows execution of arbitrary Java classes with parameterless constructors and their String-parameter methods via reflection. The vulnerability leverages the eval method in Tomcat's jakarta.el.ELProcessor class to execute commands remotely.
