ALSA-2026:35841 — Important: nodejs24 security, bug fix, and enhancement update

Affected: AlmaLinux:10: nodejs24, AlmaLinux:10: nodejs24-devel, AlmaLinux:10: nodejs24-docs, AlmaLinux:10: nodejs24-full-i18n, AlmaLinux:10: nodejs24-libs, AlmaLinux:10: nodejs24-npm

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.

fkie_cve-2026-9678

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.

GHSA-pr7r-676h-xcf6 — undici vulnerable to cross-user information disclosure via shared cache whitespace bypass

Affected: npm: undici

## 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.

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.
