CVE-2026-115895

A flaw was found in happy-dom. This vulnerability allows an attacker to achieve arbitrary code execution within the host Node.js environment. When JavaScript evaluation is enabled, the module compiler fails to validate named ECMAScript Module ESM import aliases before inserting them into generate...
