CVE-2026-12644: Incomplete Object Property Blocklist
An incomplete blocklist was used to filter object keys. Filtering properties like `__proto__` and `constructor` but failing to filter essential `Object.prototype` properties like `toString`, `valueOf`, and `hasOwnProperty` can lead to application crashes (DoS) when overridden properties are unexpectedly executed. Consider validating against an extensive list
