{"schema":"threatline.record/2","record":{"id":"CVE-2026-16762","aliases":[],"summary":"Denial-of-service vulnerability in the Qt Core QXmlStream parser (QXmlStreamReader) impacts Qt","details":"An attacker able to supply a crafted XML document to an application using QXmlStreamReader can cause disproportionate CPU consumption during parsing, making the application unresponsive (denial of service). Exploitation requires only that the application parse attacker-influenced XML; no authentication, privileges, or user interaction beyond ingesting the input are needed. There is no loss of confidentiality or integrity — no data disclosure, data modification, or code execution — and the impact is contained to the affected process.","categories":["Unclassified"],"product":"qt","vendor":"qt","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-16762","source_modified_at":"2026-10-23T10:56:05.830Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"qt","vendor":"qt","versions":[{"status":"unknown","version":"0","lessThan":"4.3.0","versionType":"python"},{"status":"affected","version":"4.3.0","lessThan":"6.8.9","versionType":"python"},{"status":"affected","version":"6.9.0","lessThan":"6.11.2","versionType":"python"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-16762","source_modified_at":"2026-10-23T10:56:05.830Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"qt","ecosystem":null},"version":"6.8.9","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-16762","source_modified_at":"2026-10-23T10:56:05.830Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"qt","ecosystem":null},"version":"6.11.2","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00426,"percentile":0.35872,"score_date":"2026-10-23"},"published_at":"2026-10-23T08:58:40.028Z","modified_at":"2026-10-23T10:56:05.830Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-16762","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T10:56:05.830Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-16762","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://wiki.qt.io/List_of_known_vulnerabilities_in_Qt_products#CVE-2026-16762:","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://codereview.qt-project.org/c/qt/qtbase/+/738885","tags":["patch"]},{"source":"CVE List","url":"https://codereview.qt-project.org/c/qt/qtbase/+/738901","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-23T10:43:53.436456Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T10:56:05.830Z","content_hash":"34e3ea911f2b6957d7f8e9053fc9452acd5ad58b8f76b91e4e2b14ba7ffe136e"}}
