Red Hat Security Advisory: nodejs24 security, bug fix, and enhancement update
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): * 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) * undici: undici: Man-in-the-Middle attack via ignored TLS options with SOCKS5 proxy (CVE-2026-9697) * undici: undici: Information disclosure and data integrity issues due to incorrect Socks5ProxyAgent connection routing (CVE-2026-6734) * 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): * nodejs24: Rebase to the latest Node.js 24 release [rhel-10.2.z] (JIRA:RHEL-186582) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Technical Summary
Red Hat issued security advisories RHSA-2026:35841 and RHSA-2026:39868 providing updates for Node.js 24 and related packages on Red Hat Enterprise Linux 8 and 10. The updates fix multiple security issues including CVE-2026-6733 (undici response queue poisoning on reused keep-alive sockets), CVE-2026-12151 (undici denial of service via unbounded memory growth), CVE-2026-42338 (ip-address cross-site scripting), CVE-2026-48619 (Node.js denial of service via unlimited HTTP/2 ORIGIN frames), and others affecting TLS hostname verification, cookie SameSite policy, proxy credential disclosure, and authentication bypass. The advisories include a rebase to the latest Node.js 24 release and address a total of 15 CVEs. The fixes are provided as RPM package updates for multiple architectures and Red Hat Enterprise Linux versions.
Potential Impact
The vulnerabilities fixed include denial of service conditions, information disclosure, cross-site scripting, authentication bypass, and response queue poisoning that could lead to incorrect response delivery. These issues could impact the security and reliability of applications running Node.js 24 on affected Red Hat Enterprise Linux systems. The severity is rated as Important, indicating a high impact on confidentiality, integrity, or availability if exploited.
Mitigation Recommendations
Red Hat has released updated packages for Node.js 24 and related components that address all listed vulnerabilities. Users should apply the provided updates for their respective Red Hat Enterprise Linux versions and architectures as soon as possible. The vendor advisory confirms that these updates include official fixes. Refer to the Red Hat advisory articles (https://access.redhat.com/articles/11258) for detailed instructions on applying the updates.
