Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of org.drools:drools-core before 7.60.0.Final are affected by an XML External Entity (XXE) vulnerability in the KieModuleMarshaller class, where the XML validator is not used correctly. The source does not describe what an attacker must do to trigger it or the exact impact, though XXE flaws can allow reading local files or server-side requests. Upgrade org.drools:drools-core to 7.60.0.Final or later.
