Jenkins AbsInt a³ Plugin 1.1.0 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows attackers able to control `Project File (APX)` contents 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.
