The French CERT has issued an advisory for multiple vulnerabilities discovered in Node.js runtime versions 22.x (prior to 22.23.0), 24.x (prior to 24.17.0), and 26.x (prior to 26.3.1). The vulnerabilities enable attackers to perform remote denial of service attacks, compromise data confidentiality and integrity, and bypass security policies.
Thirteen CVEs were assigned to these flaws (CVE-2026-21636, CVE-2026-48615, CVE-2026-48617, CVE-2026-48618, CVE-2026-48619, CVE-2026-48928, CVE-2026-48930, CVE-2026-48931, CVE-2026-48933, CVE-2026-48934, CVE-2026-48935, CVE-2026-48936, CVE-2026-48937). The Node.js project released security updates on June 18, 2026 to address these issues. Organizations running affected versions should refer to the official Node.js security bulletin and apply the patches to the latest versions in each release line.

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 16,433 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.
