Name of the Vulnerable Software and Affected Versions Jenkins Phabricator Differential Plugin versions 2.1.5 and earlier

Description The issue is related to the configuration of the XML parser, which does not prevent XML external entity (XXE) attacks. This allows attackers who can control coverage report file contents for the Post to Phabricator post-build action to have Jenkins parse a crafted XML document, potentially leading to the extraction of secrets from the Jenkins controller or server-side request forgery.

Recommendations For Jenkins Phabricator Differential Plugin versions 2.1.5 and earlier, consider disabling the XML parser or restricting its use until a patch is available. As a temporary workaround, restrict access to the Post to Phabricator post-build action to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
