Important: nodejs22 security update

Published Apr 12, 2026 · Updated Apr 12, 2026

Ecosystem: Rocky Linux

Summary

Node.js is a platform built on Chrome's JavaScript runtime \ for easily building fast, scalable network applications. \ Node.js uses an event-driven, non-blocking I/O model that \ makes it lightweight and efficient, perfect for data-intensive \ real-time applications that run across distributed devices.

Security Fix(es):

* brace-expansion: brace-expansion: Denial of Service via unbounded brace range expansion (CVE-2026-25547)

* minimatch: minimatch: Denial of Service via specially crafted glob patterns (CVE-2026-26996)

* minimatch: Minimatch: Denial of Service via catastrophic backtracking in glob expressions (CVE-2026-27904)

* undici: undici: Denial of Service via unbounded memory consumption during WebSocket permessage-deflate decompression (CVE-2026-1526)

* undici: Undici: Denial of Service via invalid WebSocket permessage-deflate extension parameter (CVE-2026-2229)

* undici: Undici: HTTP Request Smuggling and Denial of Service due to duplicate Content-Length headers (CVE-2026-1525)

* undici: undici: Denial of Service via crafted WebSocket frame with large length (CVE-2026-1528)

* nghttp2: nghttp2: Denial of Service via malformed HTTP/2 frames after session termination (CVE-2026-27135)
