Node.js Issues October 2026 Security Releases Fixing 10 Vulnerabilities
On October 21, 2026, the Node.js project released security updates for its 26.x, 24.x and 22.x lines. The advisory covers 10 vulnerabilities, including four rated High and three rated Medium. The most serious flaw is a memory-corruption bug in the bundled Brotli decoder that could enable remote code execution, prompting urgent patching. No workarounds exist, so upgrading is the only fix, and end-of-life versions such as Node.js 20 and earlier receive no patch and must be moved to a supported release.
