Attackers can split expressions across text nodes separated by disallowed elements, which merge after removal and are evaluated by downstream template engines for cross-site scripting.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-cg2g-xh64-v4q7","tags":[]},{"url":"https://www.vulncheck.com/advisories/dompurify-from-3.4.4-before-3.4.17-safe-for-templates-bypass-via-shadow-root-content","tags":[]}],"exploitRefs":[{"url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-cg2g-xh64-v4q7","tags":[]}],"hasPoc":true,"ai":null}
