CVE-2026-9747

Estado: AnalizadaAlta (7.1)—

Adding fromRouter:true and runtimeConstants.userRoles could cause aggregations to crash mongodb server.

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.

AV:N, PR:L requiere red y privilegios; crash de servidor por agregaciones malformadas es DoS de aplicación (T1499.004). CWE-617 sugiere lógica floja que se explota remotamente.

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.
