提交 #856016: Node.js compromise 14.15.1 Prototype Pollution

compromise version 14.15.1 is affected by a prototype pollution vulnerability through the public root API nlp.extend(plugin). When a plugin object contains a model property, the extension flow recursively merges plugin.model into the internal model. The recursive merge processes attacker-controlled keys without rejecting prototype-pollution primitives such as __proto__, constructor, or prototype.

A crafted plugin model containing __proto__ can cause the merge logic to descend through Object.prototype and assign attacker-controlled properties to the shared prototype. Applications that load or construct Compromise plugins from user-controlled or partially user-controlled input may allow an attacker to pollute Object.prototype, affecting later object property lookups, default options, configuration merging, feature flags, or authorization logic.
