Source: node-dottie

Severity: important

Hi,

The following vulnerability was published for node-dottie.

CVE-2026-27837[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
