Summary

Important: nodejs22 security, bug fix, and enhancement update

Details

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)
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):

nodejs22: Rebase to the latest Node.js 22 release [almalinux-10.2.z] (JIRA:AlmaLinux-186623)

CVE-2026-6733 (GCVE-0-2026-6733)

Vulnerability from cvelistv5 – Published: 2026-06-17 17:14 – Updated: 2026-06-17 18:30

Title

undici vulnerable to HTTP response queue poisoning via keep-alive socket reuse

Summary

Impact: Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets. An attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after a request completes. When the client dispatches the next request on that socket, it associates the injected response with the new request, causing responses to be delivered to the wrong requests. This requires an attacker-controlled or compromised upstream HTTP/1.1 server and keep-alive connection reuse. Patches: Upgrade to undici v6.26.0, v7.28.0 or v8.5.0. Workarounds: Disable keep-alive connection reuse by setting keepAliveTimeout: 0 on the Client or Pool.

Severity

3.7 (Low)

CVE-2026-9678 (GCVE-0-2026-9678)

Vulnerability from cvelistv5 – Published: 2026-06-17 17:04 – Updated: 2026-06-17 18:05

Title

undici vulnerable to cross-user information disclosure via shared cache whitespace bypass

Summary

Impact: Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-Control header uses whitespace-padded qualified private or no-cache field names such as private=" authorization" or no-cache="\tauthorization". The parser preserves the surrounding whitespace, so later comparisons against the literal authorization field name fail and the response is stored. In shared-cache mode, this allows a response containing one user's authenticated data to be served from cache to a subsequent caller, including an unauthenticated caller, when both requests resolve to the same cache key. Affected applications are those that explicitly enable the cache interceptor (interceptors.cache()) in shared mode, forward Authorization headers upstream, and receive cacheable responses with non-canonical qualified private or no-cache directives. Patches: Upgrade to undici v7.28.0 or v8.5.0. Workarounds: If upgrade is not immediately possible, disable shared-cache mode for traffic that includes Authorization headers, avoid caching responses to authenticated requests, or add Vary: Authorization upstream.
