Overview
org.webjars.npm:dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG.
Affected versions of this package are vulnerable to Improper Initialization in the DOMPurify.setConfig() API when an uponSanitizeAttribute hook is registered that mutates allowedAttributes. An attacker can cause persistent modification of the attribute allowlist by submitting specially crafted content, resulting in unauthorized attributes being permitted in all subsequent sanitization calls.
