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.","cvss_v4":{"vector":"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","score":5.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2","https://www.vulncheck.com/advisories/dompurify-before-3.4.16-xss-via-in-place-returned-rawtext-root","https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-109345","score":0.0025,"percentile":0.16167,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6688-9rhm-gjv2","url":"https://osv.dev/vulnerability/GHSA-6688-9rhm-gjv2","summary":"DOMPurify: IN_PLACE returns a force-removed rawtext root whose text carries attacker markup — pure HTML reparse executes","modified":"2026-10-13T02:56:32.032824370Z","packages":[{"ecosystem":"npm","name":"dompurify","purl":"pkg:npm/dompurify","ranges":["<3.4.16"],"fixed":["3.4.16"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
