Dom4j contains a XML Injection vulnerability

[slachiewicz]

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.

Requires upgrade of Doxia stack to version 2.x when available doxia-site-renderer -> velocity-tools 2.0 -> dom4j
