Dottie vulnerable to prototype pollution bypass via non-first path segments in set() and transform()
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.
Versions of the package dottie before 2.0.4 are vulnerable to Prototype Pollution due to insufficient checks, via the set() function and the current variable in the /dottie.js file.
