{"schema":"threatline.record/2","record":{"id":"CVE-2026-18320","aliases":[],"summary":"CVE-2026-18320","details":"Readwise Reader for Android uses a sanitize-html configuration that permits all attributes on SVG and PATH elements due to a wildcard attribute rule. This configuration fails to remove script-capable attributes such as event handlers (e.g., 'onload', 'onerror'). An attacker could supply a document containing malicious SVG content that survives sanitization and executes script wher rendered in the Reader WebView, resulting in client-side cross-site scripting (XSS).","categories":["Unclassified"],"product":"Reader","vendor":"Readwise","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-18320","source_modified_at":"2026-09-25T16:57:42.082Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Reader","vendor":"Readwise","versions":[{"status":"affected","version":"8.7.2","lessThan":"8.10.1","versionType":"custom"}],"defaultStatus":null}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-18320","source_modified_at":"2026-09-25T16:57:42.082Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Reader","ecosystem":null},"version":"8.10.1","basis":"first unaffected version stated in the CVE record"}],"cvss":6.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00157,"percentile":0.04512,"score_date":"2026-10-23"},"published_at":"2026-09-25T16:27:37.419Z","modified_at":"2026-09-25T16:57:42.082Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-18320","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T16:57:42.082Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-18320","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://kb.cert.org/vuls/id/699627"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-25T16:56:55.358504Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T16:57:42.082Z","content_hash":"4d99f6d178a0ed0d1ff9c1b962b6770acd8c03daa7b98bca97aa91862d7ee9ff"}}
