CVE-2025-67843

Estado: AnalizadaCrítica (9.8)—

A Server-Side Template Injection (SSTI) vulnerability in the MDX Rendering Engine in Mintlify Platform before 2025-11-15 allows remote attackers to execute arbitrary code via inline JSX expressions in an MDX file.

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.

SSTI en motor de renderizado MDX accesible remotamente sin autenticación (AV:N/PR:N) permite ejecución arbitraria de código JSX; potencial acceso a datos del servidor.

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.
