Prior to 6.1.0, constructing msgpack5 with an empty or partial options object disables the default protoAction: &#39;error&#39; protection. A decoded map containing a __proto__ key can then replace the decoded object&#39;s prototype, potentially changing inherited properties or downstream behavior, although Object.prototype is not modified globally. This issue is fixed in version 6.1.0.</p> <p><strong>Affected:</strong> mcollina msgpack5</p> <p>msgpack5 is a msgpack v5 implementation for node.js and the browser.
