Attackers can supply a style element containing a closing style tag and an img onerror payload, which executes script when the application serializes and re-parses the returned node.","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-6688-9rhm-gjv2","tags":[]},{"url":"https://www.vulncheck.com/advisories/dompurify-before-3.4.16-xss-via-in-place-returned-rawtext-root","tags":[]},{"url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2","tags":[]}],"exploitRefs":[{"url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2","tags":[]},{"url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2","tags":[]}],"hasPoc":true,"ai":null}
