CVE-2026-114613MessagePack is the serializer implementation for Python msgpack.org Executive summary This advisory concerns MessagePack, a serializer implementation for Python. The text provided is a code diff of the msgpack project rather than a vulnerability description, so the advisory does not state a severity rating or a clear impact for defenders. The vendor's recommended action is not stated. Technical summary The advisory text contains only source code diff changes to msgpack's _unpacker.pyx, unpack.h, and unpack_container_header.h files, with no vulnerability class, CVSS score, or attack vector explicitly described. The changes refactor object ownership handling, add RuntimeError and ValueError checks for reentrant or mixed unpacking calls, and adjust reference counting in map and array callbacks. Whether these changes fix a memory safety flaw, what the affected versions are, and what the fixed versions are, are not stated. Workarounds and detection guidance are not stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
