Node.js patches Brotli flaw that can enable remote code execution

OpenAI researchers found an out-of-bounds write in Brotli, a compression library bundled with Node.js, that can let attackers run code through crafted compressed data. Node.js released fixes on 21 October 2026 for its supported 22.x, 24.x and 26.x lines; the updates also address other security flaws and block compromised eMudhra certificates, according to heise online.

Bottom line — Node.js users should update to 22.23.4, 24.22.1 or 26.12.1; unsupported release lines are also affected.
