Red Hat Security Advisory: nodejs24 security 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): * nodejs: Nodejs denial of service (CVE-2026-21637) * 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) * undici: Undici: Denial of Service due to uncontrolled resource consumption (CVE-2026-2581) * undici: Undici: HTTP header injection and request smuggling vulnerability (CVE-2026-1527) * 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) * Node.js: Node.js: Denial of Service via malformed Internationalized Domain Name processing (CVE-2026-21712) * Node.js: Node.js: Denial of Service due to crafted HTTP `__proto__` header (CVE-2026-21710) * Node.js: Node.js: Information disclosure due to `fs.realpathSync.native()` bypassing filesystem read restrictions (CVE-2026-21715) * nodejs: Node.js: Permission bypass allows unauthorized modification of file permissions and ownership via incomplete security fix. (CVE-2026-21716) * Node.js: Node.js: Unauthorized inter-process communication due to missing Unix Domain Socket permission checks (CVE-2026-21711) * Node.js: Node.js: Information disclosure via timing oracle in HMAC verification (CVE-2026-21713) * Node.js: Node.js: Memory leak and Denial of Service via crafted HTTP/2 WINDOW_UPDATE frames (CVE-2026-21714) * nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions (CVE-2026-21717) 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.
AI Analysis
Technical Summary
This Red Hat security advisory (RHSA-2026:7675) covers a comprehensive set of 18 vulnerabilities affecting nodejs24 on Red Hat Enterprise Linux 10. The issues include denial of service vulnerabilities caused by malformed HTTP/2 frames, crafted WebSocket frames, unbounded memory consumption, and predictable hash collisions in V8. Other vulnerabilities include HTTP header injection, request smuggling, information disclosure via timing or filesystem bypass, permission bypass allowing unauthorized file permission changes, and missing Unix Domain Socket permission checks leading to unauthorized inter-process communication. The advisory references multiple CVEs such as CVE-2026-1525, CVE-2026-21716, and CVE-2026-26996, among others. The update is rated as important by Red Hat and addresses these vulnerabilities by patching the affected components in nodejs24 packages for Red Hat Enterprise Linux 10 across multiple architectures.
Potential Impact
The vulnerabilities collectively allow attackers to cause denial of service conditions, potentially leading to service disruption. Some flaws permit information disclosure, unauthorized modification of file permissions and ownership, and unauthorized inter-process communication. HTTP request smuggling and header injection vulnerabilities could facilitate further attacks on network communications. These issues impact the security and reliability of Node.js applications running on affected Red Hat Enterprise Linux 10 systems.
Mitigation Recommendations
A security update for nodejs24 is available from Red Hat for Red Hat Enterprise Linux 10. Users should apply the update as described in the Red Hat advisory RHSA-2026:7675 and the referenced article https://access.redhat.com/articles/11258 to remediate these vulnerabilities. No additional mitigation steps are indicated beyond applying the official update.
