CVE-2026-27837
February 26, 2026
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.
