Jenkins Phabricator Differential Plugin vulnerable to XML external entity (XXE) attacks
Jenkins Phabricator Differential Plugin 2.1.5 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
This allows attackers able to control coverage report file contents for the Post to Phabricator post-build action to have Jenkins parse a crafted XML document that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
