Summary
Important: nodejs:22 security, bug fix, and enhancement update
Details

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language.

Security Fix(es):

  • ip-address: ip-address: Cross-site scripting via improper HTML escaping of untrusted input (CVE-2026-42338)

  • undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames (CVE-2026-12151)

  • undici: Undici: Information disclosure due to improper cache-control header parsing (CVE-2026-9678)

  • undici: Undici: Response queue poisoning on reused keep-alive sockets can lead to incorrect response delivery. (CVE-2026-6733)

  • undici: undici: Weakening of cookie SameSite policy due to incorrect parsing of Set-Cookie header (CVE-2026-11525)

  • nodejs: Node.js: Denial of Service via unlimited HTTP/2 ORIGIN frames (CVE-2026-48619)

  • nodejs: Node.js: Silent authority rebinding due to embedded-nul hostnames in TLS handling (CVE-2026-48930)

  • nodejs: Node.js: Unauthorized file metadata modification (CVE-2026-48935)

  • nodejs: Node.js WebCrypto: Denial of Service via large input to subtle.encrypt() (CVE-2026-48933)

  • nodejs: Node.js: Certification validation bypass in TLS host verification (CVE-2026-48934)

  • Node.js: Node.js: Trust-policy bypass due to hostname matching inconsistency (CVE-2026-48928)

  • nodejs: Node.js: Information disclosure of proxy credentials via proxy tunnel error handling (CVE-2026-48615)

  • nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch (CVE-2026-48618)

Bug Fix(es) and Enhancement(s):

  • nodejs:22/nodejs: Rebase to the latest Node.js 22 release [rhel-8] (JIRA:Rocky Linux-176170)
