[org.jenkins-ci.plugins:cobertura] XXE vulnerability in Jenkins Cobertura Plugin

Cobertura Plugin 1.15 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 ‘Publish Cobertura Coverage Report’ post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Cobertura Plugin 1.16 disables external entity resolution for its XML parser.
