{"id":"CVE-2026-109345","summary":"DOMPurify before 3.4.16 XSS via IN_PLACE Returned Rawtext Root","details":"DOMPurify before 3.4.16 contains a cross-site scripting vulnerability that allows attackers to bypass sanitization because IN_PLACE mode returns a force-removed style element whose text content still carries markup. 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.","aliases":["GHSA-6688-9rhm-gjv2"],"modified":"2026-10-13T02:46:43.823625835Z","published":"2026-10-12T16:05:29.905Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109345.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109345.json"},{"type":"ADVISORY","url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109345"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/dompurify-before-3.4.16-xss-via-in-place-returned-rawtext-root"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cure53/dompurify","events":[{"introduced":"0"},{"fixed":"b9b9d80f7e401771c2ccaef5f45def7eec8f27d7"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.4.16"}],"source":"AFFECTED_FIELD"}}],"versions":["3.4.15","3.4.14","3.4.13","3.4.12","3.4.11","3.4.10","3.4.9","3.4.8","3.4.7","3.4.6","3.4.5","3.4.4","3.4.3","3.4.2","3.4.1","3.4.0","3.3.3","3.2.3","3.1.3","3.0.4","2.4.3","2.4.2","2.4.1","2.4.0","2.3.12","2.3.11","2.3.10","2.3.9","2.3.8","2.3.6","2.3.5","2.3.4","2.3.3","2.3.2","2.3.1","2.3.0","2.2.9","2.2.8","2.2.7","2.2.6","2.2.4","2.2.3","2.2.2","2.2.0","2.1.1","2.1.0","2.0.17","2.0.16","2.0.15","2.0.14","2.0.13","2.0.12","2.0.11","2.0.10","2.0.9","2.0.8","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","1.0.11","1.0.10","1.0.9","1.0.8","1.0.7","1.0.6","1.0.5","1.0.4","1.0.3","1.0.2","1.0.1","1.0.0","0.9.0","0.8.9","0.8.8","0.8.7","0.8.6","0.8.5","0.8.4","0.8.3","0.8.2","0.8.1","0.8.0","0.7.3","0.7.2","0.7.1","0.7.0","0.6.7","0.6.6","0.6.5","0.6.4","0.6.3","0.6.2","0.6.1","0.6.0","0.4.5","0.4.4","0.4.3","0.4.2","0.4","0.3","v0.3","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109345.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}]}
