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.","categories":["Libraries & packages"],"product":"DOMPurify","vendor":"cure53","ecosystem":"npm","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109345","source_modified_at":"2026-10-13T17:40:08.757Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"DOMPurify","vendor":"cure53","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"3.4.16"},{"version":"3.4.16","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-6688-9rhm-gjv2","source_modified_at":"2026-10-13T02:56:32.032824370Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"dompurify","ecosystem":"npm","purl":"pkg:npm/dompurify"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.4.16"}]}],"versions":[]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109345","source_modified_at":"2026-10-13T17:40:08.757Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"DOMPurify","ecosystem":null},"version":"3.4.16","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-6688-9rhm-gjv2","source_modified_at":"2026-10-13T02:56:32.032824370Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"dompurify","ecosystem":"npm","purl":"pkg:npm/dompurify"},"version":"3.4.16"}],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00204,"percentile":0.09882,"score_date":"2026-10-23"},"published_at":"2026-10-12T16:05:29.905Z","modified_at":"2026-10-13T17:40:08.757Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109345","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T17:40:08.757Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-6688-9rhm-gjv2","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T02:56:32.032824370Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109345","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-6688-9rhm-gjv2","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/dompurify-before-3.4.16-xss-via-in-place-returned-rawtext-root","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T17:39:41.683886Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-13T17:40:08.757Z","content_hash":"d77fffd24f151f8b9a363b1b8bd6b4bdf83e6b9348eae551a1d92740dd7dbf8f"}}
