CVE-2025-15599

DOMPurify XSS via Textarea Rawtext Bypass in SAFE_FOR_XML

Published Mar 3, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
DOMPurify 3.1.3 through 3.2.6 and 2.5.3 through 2.5.8 contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting missing textarea rawtext element validation in the SAFE_FOR_XML regex. Attackers can include closing rawtext tags like </textarea> in attribute values to break out of rawtext contexts and execute JavaScript when sanitized output is placed inside rawtext elements. The 3.x branch was fixed in 3.2.7; the 2.x branch was never patched.
