{"id":"CVE-2019-6446","aliases":["GHSA-9fq2-x9r6-wfmf","PYSEC-2019-108"],"url":"https://o3.security/vulnerability/CVE-2019-6446","summary":"Numpy Deserialization of Untrusted Data","details":"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":"2019-01-16T05:29:01.370Z","modified":"2026-07-25T18:29:57.061179458Z","cvss":{"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"},"epss":null,"cisaKev":null,"exploitsKnown":4,"affectedPackages":[{"ecosystem":"PyPI","name":"numpy","fixedVersion":"1.16.3"}],"fix":{"url":"https://github.com/numpy/numpy/commit/89b688732b37616c9d26623f81aaee1703c30ffb","label":"numpy/numpy@89b6887"},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00091.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00092.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00015.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7ZZAYIQNUUYXGMKHSPEEXS4TRYFOUYE4/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/7ZZAYIQNUUYXGMKHSPEEXS4TRYFOUYE4/"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106670"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3335"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3704"},{"type":"REPORT","url":"https://bugzilla.suse.com/show_bug.cgi?id=1122208"},{"type":"REPORT","url":"https://github.com/numpy/numpy/issues/12759"},{"type":"FIX","url":"https://github.com/numpy/numpy/commit/89b688732b37616c9d26623f81aaee1703c30ffb"},{"type":"FIX","url":"https://github.com/numpy/numpy/pull/12889"},{"type":"FIX","url":"https://github.com/numpy/numpy/pull/13359"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-25T18:29:57.061179458Z"}}
