Puntuación base: 9.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.67%
Percentil entre todas las CVEs puntuadas: 50
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1195 Supply Chain Compromiseinitial access85 %
Impacto principalT1212 Exploitation for Credential Accesscredential access90 %

CWE-506 (credential harvesting) y CWE-829 (cadena de suministro) en versiones específicas de PyTorch Lightning sugieren manipulación intencional del paquete para capturar credenciales, no explotación remota clásica sino compromiso de la cadena de suministro.

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.
