CVE-2019-6446
Status: ModifiedCritical (9.8)—💥 PoC
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.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Base score: 9.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 18%
- Percentile among all scored CVEs: 97
- Score date: 10/18/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

Emplea el módulo de Python pickle de forma insegura, lo que permite que los atacantes remotos ejecuten código arbitrario mediante un objeto serializado, tal y como queda demostrado con una llamada numpy.load. NOTA: hay terceros que discuten este problema, ya que es un comportamiento que podría tener aplicaciones legítimas en, por ejemplo, la carga de arrays de objetos de Python serializados de fuentes fiables y autenticadas."
