CVE-2026-0540 is fixed in node-dompurify on 1 platform by DEBIAN-CVE-2026-0540 (version 3.3.2+dfsg-1), released March 3, 2026. It is not reported as exploited. Patch Radar priority: Routine.
DOMPurify 3.1.3 through 3.3.1 and 2.5.3 through 2.5.8, fixed in commit 2726c74, contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting five missing rawtext elements (noscript, xmp, noembed, noframes, iframe) in the SAFE_FOR_XML regex. Attackers can include payloads like </noscript><img src=x onerror=alert(1)> in attribute values to execute JavaScript when sanitized output is placed inside these unprotected rawtext contexts.
