CyberRota Analysis
AI-GeneratedThe msgpack-java library versions up to 0.9.12 are vulnerable to a stack overflow due to unbounded recursive deserialization of arrays and maps in the MessageUnpacker.unpackValue() method. This flaw allows attackers to create payloads with deeply nested structures, potentially leading to denial-of-service conditions through StackOverflowError during deserialization. Java developers and organizations utilizing this library should prioritize patching to mitigate the risk of service disruptions.

Original NVD Description
msgpack-java through 0.9.12 contains a stack overflow vulnerability in MessageUnpacker.unpackValue() that recursively deserializes arrays and maps without nesting depth limits. Attackers can craft payloads with deeply nested arrays to exhaust the deserializing thread's stack and trigger StackOverflowError, causing per-request deserialization failures.
