CVE-2026-27837 (GCVE-0-2026-27837)

Vulnerability from cvelistv5 – Published: 2026-02-26 00:19 – Updated: 2026-02-26 14:40
VLAI?
Title
Dottie vulnerable to prototype pollution bypass via non-first path segments in set() and transform()
Summary
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.
Severity ?
