The vulnerability stemmed from using getOwn/getOwnTruthy methods that checked the prototype chain. The commit replaced them with get/getTruthy using a mitigation that stops at Object.prototype. Affected functions are those processing user-input objects via these methods before the fix. High confidence due to explicit security-focused code changes in the commit diff across multiple API endpoints.
