  "description": "Dottie provides nested object access and manipulation in JavaScript. Versions 2.0.4 through 2.0.6 contain an incomplete fix for CVE-2023-26132. The prototype pollution guard introduced in commit \u00607d3aee1\u0060 only validates the first segment of a dot-separated path, allowing an attacker to bypass the protection by placing \u0060__proto__\u0060 at any position other than the first. Both \u0060dottie.set()\u0060 and \u0060dottie.transform()\u0060 are affected. Version 2.0.7 contains an updated fix to address the residual vulnerability.",
