Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
cyclonedx-core-java versions from 2.1.0 before 9.0.4 are affected. An attacker who can supply an XML bill of materials for the library to parse can exploit an XML external entity flaw to read local files or make server-side requests. Upgrade to 9.0.4. If that is not possible, reject XML input before parsing when BOMs are known to be JSON.
