Jenkins External Monitor Job Type Plugin 206.v9a_94ff0b_4a_10 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers with Item/Build permission to have Jenkins parse a crafted HTTP request with XML data that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

External Monitor Job Type Plugin 207.v98a_a_37a_85525 disables external entity resolution for its XML parser.
