CVE-2026-41239

A flaw was found in DOMPurify. A remote attacker could exploit this cross-site scripting (XSS) vulnerability when DOMPurify is configured to return a Document Object Model (DOM) or DOM fragment. The SAFE_FOR_TEMPLATES feature, intended to strip template expressions like {{...}}, fails in these modes, allowing malicious content to bypass sanitization. This can lead to arbitrary code execution or information disclosure in applications utilizing template-evaluating frameworks such as Vue 2.
