    Arbitrary Code Injection

    happy-dom is a Happy DOM is a JavaScript implementation of a web browser without its graphical user interface. It includes many web standards from WHATWG DOM and HTML.

    Affected versions of this package are vulnerable to Arbitrary Code Injection via the ESM compiler (ECMAScriptModuleCompiler.ts), which fails to validate import alias default-value expressions in ES module source text before passing them to an evaluator. An attacker who can cause a page to load a module script containing an import binding with an injected default-value expression (e.g. import { missing as x = <arbitrary JS> } from '...') can achieve arbitrary code execution on the host Node.js process, including access to the filesystem through process.getBuiltinModule.

    How to fix Arbitrary Code Injection?

    Upgrade happy-dom to version 21.0.4 or higher.
