## What to check

- Applies to: The 19 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR issued an advisory covering multiple vulnerabilities in Node.js affecting versions prior to 22.23.5, 24.22.3, and 26.13.1. The flaws, detailed in Node.js's November 2026 security release bulletin, can lead to confidentiality breaches, security policy bypass, and denial of service conditions. No exploitation in the wild is mentioned in the advisory.

The advisory references 19 CVEs, including one older CVE (CVE-2024-27983) and several newly assigned 2026 CVEs. CERT-FR recommends referring to the official Node.js security bulletin for patches and applying updates to the fixed versions as soon as possible.

Defenders running Node.js in production or development environments should inventory affected versions and prioritize upgrading to 22.23.5, 24.22.3, or 26.13.1 or later to mitigate the described risks.
