Chainguard: multiple nodejs-22 packages: security update to 22.22.3-r0

medium Tenable Cloud Security Plugin ID 477883

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided
 signatures, potentially leaking timing information proportional to the number of matching bytes. Under
 certain threat models where high-resolution timing measurements are possible, this behavior could be
 exploited as a timing oracle to infer HMAC values. Node.js already provides timing-safe comparison
 primitives used elsewhere in the codebase, indicating this is an oversight rather than an intentional
 design decision. This vulnerability affects **20.x, 22.x, 24.x, and 25.x**. (CVE-2026-21713)

Solution

Update the nodejs-22 library and its related packages to version 22.22.3-r0 or later.
