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.

EUVD-2026-366752

fkie_cve-2026-12151

Affected applications are those using the undici WebSocket client (new WebSocket(...)) or the WebSocketStream API that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint.

All releases starting at undici 6.17.0 are affected.

Patches: Upgrade to undici >= 6.26.0, >= 7.28.0, or >= 8.5.0. Workarounds: No workaround is available. The fix must be applied through an upgrade.

GHSA-vxpw-j846-p89q — undici WebSocket client vulnerable to denial of service via fragment count bypass

Affected: npm: undici

## Impact

The undici WebSocket client enforces `maxPayloadSize` on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that each pass per-frame and cumulative-size validation, collectively causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of service.

Affected applications are those using the undici WebSocket client (`new WebSocket(...)`) or the `WebSocketStream` API that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint.

All releases starting at undici 6.17.0 are affected.

## Patches

Upgrade to undici v6.27.0, v7.28.0 or v8.5.0.

## Workarounds

No workaround is available. The fix must be applied through an upgrade.
