Cross-site Scripting (XSS)

Overview dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG. Affected versions of this package are vulnerable to Cross-site Scripting XSS in the SAFEFORTEMPLATES function. An attacker can inject template expressions that survive sanitization inside element content by splitting malicio...

DOMPurify: SAFE_FOR_TEMPLATES bypass - template expressions survive sanitization inside <template> content when using DOM output modes

Summary When DOMPurify is configured with both SAFEFORTEMPLATES: true and RETURNDOM: true or INPLACE: true, an attacker can inject template expressions, such as $evil, evil, or , that survive the sanitization pass inside element content. This bypasses the explicit purpose of SAFEFORTEMPLATES, whi...

If the HTML you give it contains a element, and inside that template there's an element with a shadow DOM attached to it, DOMPurify quietly skips over the shadow contents. Whatever the attacker put in there - an image with an onerror handler, a link with a javascript: URL, even a full script -...
