Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The hornetq-core-client package (Maven org.hornetq) in versions up to and including 2.4.9 is affected. The source gives few details: the createTempFile method can be abused to overwrite arbitrary files or read sensitive information. No fix is listed, so no patched version is named.
