CVE-2025-54886

Estado: AplazadaAlta (8.4)—

skops is a Python library which helps users share and ship their scikit-learn based models. In versions 0.12.0 and below, the Card.get_model does not contain any logic to prevent arbitrary code execution. The Card.get_model function supports both joblib and skops for model loading. When loading .skops models, it uses skops' secure loading with trusted type validation, raising errors for untrusted types unless explicitly allowed. However, when non-.zip file formats are provided, the function silently falls back to joblib without warning. Unlike skops, joblib allows arbitrary code execution during loading, bypassing security measures and potentially enabling malicious code execution. This issue is fixed in version 0.13.0.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso local sin interacción (AV:L/PR:N/UI:N) permite escalada mediante desserialización insegura (CWE-502) en joblib, logrando ejecución de código arbitrario con privilegios elevados (C:H/I:H/A:H).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

En las versiones 0.12.0 y anteriores, Card.get_model no contiene ninguna lógica que impida la ejecución de código arbitrario. La función Card.get_model admite tanto joblib como skops para la carga de modelos. Al cargar modelos .skops, utiliza la carga segura de skops con validación de tipos confiables, lo que genera errores para tipos no confiables a menos que se permita explícitamente. Sin embargo, cuando se proporcionan formatos de archivo distintos de .zip, la función recurre silenciosamente a joblib sin previo aviso. A diferencia de skops, joblib permite la ejecución de código arbitrario durante la carga, evadiendo las medidas de seguridad y potencialmente permitiendo la ejecución de código malicioso. Este problema se solucionó en la versión 0.13.0."
