RHEL 10 : nodejs22 (RHSA-2026:39246)

medium Nessus Plugin ID 326796

Synopsis

The remote Red Hat host is missing one or more security updates for nodejs22.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:39246 advisory.

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)

* nodejs: Node.js WebCrypto: Denial of Service via large input to subtle.encrypt() (CVE-2026-48933)

* 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)

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL nodejs22 package based on the guidance in RHSA-2026:39246.
