Last modified
CVE-2026-65914 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. 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.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
