CVE-2026-42302

Estado: AplazadaCrítica (9.8)—

FastGPT is an AI Agent building platform. From version 4.14.10 to before version 4.14.13, the agent-sandbox component of FastGPT is vulnerable to unauthenticated Remote Code Execution (RCE). The startup script entrypoint.sh initializes code-server with the --auth none flag and binds the service to all network interfaces (0.0.0.0:8080). This configuration allows any user with network access to the port to bypass authentication and gain full control over the sandbox environment. This issue has been patched in version 4.14.13.

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.

RCE no autenticado en servicio expuesto en red (AV:N, PR:N, UI:N). El atacante obtiene acceso sin autenticación al sandbox y ejecuta código arbitrario con permisos del contenedor.

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.
