A style or script element inside SVG or MathML foreign content is parsed with character references decoded, but is serialized as an HTML raw-text element, so its text is emitted unescaped. Encoded markup such as &lt;/style&gt;&lt;img src=x onerror=...&gt; inside <svg><style> therefore closes the element on re-parse and becomes live markup. Applications that parse untrusted HTML with lazy_html, filter the document or tree, and serialize it for display are affected, since the payload is a plain text node that no element or attribute filter sees.\n\nThis issue affects lazy_html: from 0.1.0 before 0.1.13.","categories":["Unclassified"],"product":"lazy_html","vendor":"dashbitco","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92106","source_modified_at":"2026-09-25T12:41:30.597Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"lazy_html","vendor":"dashbitco","versions":[{"lessThan":"0.1.13","status":"affected","version":"0.1.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92106","source_modified_at":"2026-09-25T12:41:30.597Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"lazy_html","vendor":"dashbitco","versions":[{"lessThan":"f32c7fd6223225b68bc8691c78b6d4a77972f1d5","status":"affected","version":"1dee15746c024916b3110af8b168c2f3b3065fbd","versionType":"git"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92106","source_modified_at":"2026-09-25T12:41:30.597Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"lazy_html","ecosystem":null},"version":"0.1.13","basis":"first unaffected version stated in the CVE record"}],"cvss":2.3,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00394,"percentile":0.3249,"score_date":"2026-10-23"},"published_at":"2026-09-25T09:33:13.051Z","modified_at":"2026-09-25T12:41:30.597Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92106","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T12:41:30.597Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92106","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/dashbitco/lazy_html/security/advisories/GHSA-8rqp-v692-v82q","tags":["related","vendor-advisory"]},{"source":"CVE List","url":"https://cna.erlef.org/cves/CVE-2026-92106.html","tags":["related"]},{"source":"CVE List","url":"https://osv.dev/vulnerability/EEF-CVE-2026-92106","tags":["related"]},{"source":"CVE List","url":"https://github.com/dashbitco/lazy_html/commit/1dee15746c024916b3110af8b168c2f3b3065fbd","tags":["related"]},{"source":"CVE List","url":"https://github.com/dashbitco/lazy_html/commit/f32c7fd6223225b68bc8691c78b6d4a77972f1d5","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-25T12:35:42.717583Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T12:41:30.597Z","content_hash":"6f600b999bf9b0e8de807b8c5878d067d3542b3f977bb4e6dad614817c3aa40c"}}
