CVE-2026-107300 · msgpack5: Many buffered values can exhaust the streaming decoder stack
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
msgpack5 is a msgpack v5 implementation for node.js and the browser. Prior to 6.1.0, the streaming decoder recursively invokes itself for each complete MessagePack value remaining in a chunk. A remote peer can send one chunk containing many small valid values, causing recursion proportional to the value count, exhausting the JavaScript call stack, and interrupting the process or stream. This issue is fixed in version 6.1.0.
