Node.js has published a series of security updates on October 21, 2026. These updates address 4 critical vulnerabilities affecting previous versions of the 22, 24, and 26 branches. This information is relevant if you have installed Node.js on your server (Cloud or dedicated) and use it to run applications. SWPanel does not manage or automatically update Node.js, so if you use it, you will need to take action yourself.
What happened
Node.js is a JavaScript runtime commonly used to develop backend applications. The published updates fix 4 high-severity security issues (CVSS: HIGH) affecting versions prior to 22.23.4, 24.22.1, and 26.12.1. These vulnerabilities include, among other things, remote code execution, TLS certificate bypass, and DNS name resolution issues. A CVE (CVE-2026-XXXXXX) is a unique identifier for each vulnerability, and CVSS (Common Vulnerability Scoring System) is a score indicating its severity.
