Details

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 7d3aee1 only validates the first segment of a dot-separated path, allowing an attacker to bypass the protection by placing __proto__ at any position other than the first. Both dottie.set() and dottie.transform() are affected. Version 2.0.7 contains an updated fix to address the residual vulnerability.
