NVD Description

Note: Versions mentioned in the description apply only to the upstream node-dompurify package and not the node-dompurify package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
