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.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,572 reports from 147 sources, 724 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
