DOMPurify versions prior to 3.3.2 are vulnerable to a mutation-XSS attack when sanitized HTML is reintegrated into specific parsing contexts, such as script or iframe elements. This flaw allows attackers to exploit closing sequences to escape the wrapper context, potentially executing malicious JavaScript. Developers and organizations utilizing DOMPurify for HTML sanitization should prioritize upgrading to the latest version to mitigate this risk.

Original NVD Description

DOMPurify before 3.3.2 contains a mutation-XSS vulnerability when sanitized HTML is reinserted into special parsing contexts using innerHTML with wrappers like script, xmp, iframe, noembed, noframes, or noscript. Attackers can craft payloads with closing sequences that break out of the wrapper context during reparsing, reactivating dangerous markup with event handlers to execute JavaScript.
