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.\n\n## Affected packages\n\n- `numpy < 1.16.3`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `numpy 1.16.3`","depth":"abyssal","depthScore":69,"depthScoreParts":{"impact":53.9,"likelihood":2.7,"exploitation":12,"ransomware":0},"changes":[{"seq":4558,"id":"CVE-2019-6446","ts":1788887190754,"field":"exploit_available","old":"false","new":"true"},{"seq":3441,"id":"CVE-2019-6446","ts":1788886308004,"field":"exploit_available","old":"true","new":"false"},{"seq":2295,"id":"CVE-2019-6446","ts":1788882977659,"field":"exploit_available","old":"false","new":"true"},{"seq":1324,"id":"CVE-2019-6446","ts":1788882389699,"field":"exploit_available","old":"true","new":"false"},{"seq":438,"id":"CVE-2019-6446","ts":1788881825537,"field":"exploit_available","old":"false","new":"true"}]}
