Machine-written summary

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

CycloneDX Core (Java) cyclonedx-core-java versions 2.1.0 up to 11.0.1 (not including 11.0.1) are vulnerable to XML External Entity injection because the XML validator is not configured securely. An attacker who can supply XML BOMs for validation may be able to read local data or cause server-side requests. Upgrade to version 11.0.1. If upgrading is not possible, reject XML input before validation, which is an option if incoming BOMs are known to be JSON.
