Summary
XXE vulnerability in Jenkins Performance Plugin
Details
Jenkins Performance Plugin 3.20 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
This allows attackers able to control workspace contents to have Jenkins parse a crafted XML report file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
As of publication of this advisory, there is no fix.

Summary
dom4j allows External Entities by default which might enable XXE attacks
Details
dom4j before 2.1.3 allows external DTDs and External Entities by default, which might enable XXE attacks. However, there is popular external documentation from OWASP showing how to enable the safe, non-default behavior in any application that uses dom4j.
Note: This advisory applies to dom4j:dom4j version 1.x legacy artifacts. To resolve this a change to the latest version of org.dom4j:dom4j is recommended.

Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
