CVE-2026-35216

Estado: AnalizadaCrítica (9)—

Budibase is an open-source low-code platform. Prior to version 3.33.4, an unauthenticated attacker can achieve Remote Code Execution (RCE) on the Budibase server by triggering an automation that contains a Bash step via the public webhook endpoint. No authentication is required to trigger the exploit. The process executes as root inside the container. This issue has been patched in version 3.33.4.

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.

Vulnerabilidad de RCE en endpoint público sin autenticación (AV:N, PR:N) en plataforma web Budibase. Ejecución de comandos Bash como root en contenedor (CWE-78, impacto crítico de integridad y disponibilidad).

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.
