[org.jenkins-ci.plugins:klocwork] XXE vulnerability in Jenkins Klocwork Analysis Plugin

Klocwork Analysis Plugin 2020.2.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows a user able to control the input files for the Klocwork plugin parser to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
