Background
The Jenkins MSTest Plugin is a Maven package (org.jvnet.hudson.plugins:mstest) used in Jenkins for integrating MSTest-based tests into the Jenkins environment. It provides functionality to execute and report on MSTest tests within Jenkins. However, versions 1.0.0 and earlier of the plugin are vulnerable to XML external entity (XXE) attacks.
