In 5.0.44 and earlier, the _.merge(target, source) utility exported by @feathersjs/commons recursively merges source into target by iterating Object.keys(source). When source was produced by JSON.parse and contains a __proto__, constructor, or prototype key, that key is returned as an own-enumerable property; the recursive merge then resolves target[&#39;__proto__&#39;] to Object.prototype and writes attacker-supplied properties onto it, polluting the prototype for all plain objects in the process for the lifetime of the Node process. This issue is fixed in version 5.0.45.</p> <p><strong>Affected:</strong> feathersjs feathers</p> <p>Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript.
