SCA: security update for happy-dom (GHSA-c8p4-j97h-3vg8)

high Tenable Self-Hosted Container Security Plugin ID 477823

Description

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

 - Happy DOM is a JavaScript implementation of a web browser without its graphical user interface. Prior to
 21.0.0, Happy DOM loads iframe src URLs and link rel="stylesheet" href URLs by default while parsing
 untrusted HTML on the server because disableIframePageLoading and disableCSSFileLoading default to false.
 An attacker who controls parsed HTML can therefore cause server-side requests to arbitrary internal or
 cloud endpoints without an application opt-in and may expose confidential responses or credentials
 returned by those endpoints. This issue is fixed in version 21.0.0. (CVE-2026-118660)

Solution

Update the happy-dom library and its related packages to version 21.0.0 or later.
