CVE-2026-50510

Estado: AnalizadaAlta (7.8)—

Improper restriction of names for files and other resources in Github Copilot allows an unauthorized attacker to execute code locally.

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 (AV:L) con privilegios limitados (PR:L) sin interacción: escalada de privilegios (T1068). CWE-641 sobre nombres de archivos permite ejecución de código local (T1059).

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.
