What to check
- Applies to
- Not tied to a specific actor, malware or CVE, only to the sectors it covers, so it may be general reporting. Check the source before acting on it. Whether it concerns you is not assessed.
CERT-FR has issued an advisory covering multiple vulnerabilities in Node.js affecting versions 22.x prior to 22.23.4, 24.x prior to 24.22.1, and 26.x prior to 26.12.1. The vulnerabilities, disclosed by the Node.js project in its October 2026 security release bulletin, include risks of remote arbitrary code execution, security policy bypass, and an issue not further specified by the vendor.
No technical details of the vulnerabilities, exploitation status, or CVE identifiers were included in this advisory. Defenders running affected Node.js versions should prioritize upgrading to the patched releases referenced in the official Node.js security bulletin. As Node.js is widely used in server-side and application infrastructure, organizations should inventory affected deployments and apply updates promptly, particularly given the remote code execution risk.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 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.
