CVE-2026-51997

Estado: AplazadaAlta (8.8)—

An issue in geelen mcp-remote 0.1.16 through 0.1.38 allows a remote attacker to execute arbitrary code via the open() functions

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.

Vector AV:N/UI:R sugiere explotación en cliente con interacción (T1203). CWE-94 (eval dinámico) y descripción de ejecución de código confirman T1059 como impacto primario. T1090 es especulativo sin detalles de red.

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.
