CVE ID :CVE-2026-33943 Published : March 27, 2026, 10:16 p.m. | 1 hour, 38 minutes ago Description :Happy DOM is a JavaScript implementation of a web browser without its graphical user interface. In versions 15.10.0 through 20.8.7, a code injection vulnerability in `ECMAScriptModuleCompiler` allows an attacker to achieve Remote Code Execution (RCE) by injecting arbitrary JavaScript expressions inside `export { }` declarations in ES module scripts processed by happy-dom. The compiler directly interpolates unsanitized content into generated code as an executable expression, and the quote filter does not strip backticks, allowing template literal-based payloads to bypass sanitization. Version 20.8.8 fixes the issue. Severity: 8.8 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...
