Описание
DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Starting in version 1.0.10 and prior to version 3.4.0, SAFE_FOR_TEMPLATES strips {{...}} expressions from untrusted HTML. This works in string mode but not with RETURN_DOM or RETURN_DOM_FRAGMENT, allowing XSS via template-evaluating frameworks like Vue 2. Version 3.4.0 patches the issue.
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.
