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.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00091.html","http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00092.html","http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00015.html","http://www.securityfocus.com/bid/106670","https://access.redhat.com/errata/RHSA-2019:3335"],"products":["fedoraproject:fedora","numpy:numpy"],"source":"nvd","synced_at":"2026-10-19T20:54:36.112582389+00:00"},"epss":{"cve":"CVE-2019-6446","score":0.17528,"percentile":0.97137,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9fq2-x9r6-wfmf","url":"https://osv.dev/vulnerability/GHSA-9fq2-x9r6-wfmf","summary":"Numpy Deserialization of Untrusted Data","modified":"2026-07-06T15:30:15.818392869Z","packages":[{"ecosystem":"PyPI","name":"numpy","purl":"pkg:pypi/numpy","ranges":["<1.16.3"],"fixed":["1.16.3"]}]},{"id":"PYSEC-2019-108","url":"https://osv.dev/vulnerability/PYSEC-2019-108","summary":"","modified":"2026-06-10T17:02:26.371473951Z","packages":[{"ecosystem":"PyPI","name":"numpy","purl":"pkg:pypi/numpy","ranges":["<1.16.1"],"fixed":["1.16.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
