{"id":"CVE-2019-6446","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-6446","generatedAt":"2026-11-04T11:42:39.874Z","title":"It uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a numpy.load call.","description":"An issue was discovered in NumPy before 1.16.3. It uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a numpy.load call. NOTE: third parties dispute this issue because it is a behavior that might have legitimate applications in (for example) loading serialized Python object arrays from trusted and authenticated sources.","published":"2019-01-16T05:29:01.000Z","lastModified":"2026-06-17T02:39:04.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-502"],"affected":["numpy/numpy","fedoraproject/fedora"],"epss":{"score":0.27266,"percentile":0.98062,"date":"2026-11-03","history":[{"date":"2026-09-21","score":0.13625,"percentile":0.96362},{"date":"2026-09-22","score":0.17528,"percentile":0.96999},{"date":"2026-11-02","score":0.27266,"percentile":0.98059}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 27.3%, higher than 98% of all known CVEs.
