CVE-2025-64518Network attack vector

Local file disclosure via external entity resolution

Published Nov 10, 2025 · Updated Nov 12, 2025

XXE injection in CycloneDX Core (Java) 2.1.0 through 11.0.0 allows remote attackers to read local files via crafted XML BOMs. CycloneDxSchema.getXmlSchema creates a SchemaFactory whose external DTD and schema access protocols remain enabled during BOM validation. Exploitation requires an application to pass attacker-controlled XML to the validation path, and the documented consequence is confidentiality loss without data modification or service interruption.
