CVE-2026-34825

Estado: AnalizadaAlta (8.5)—

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to version 2.0.30, NocoBase plugin-workflow-sql substitutes template variables directly into raw SQL strings via getParsedValue() without parameterization or escaping. Any user who triggers a workflow containing a SQL node with template variables from user-controlled data can inject arbitrary SQL. This issue has been patched in version 2.0.30.

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.

SQL injection en NocoBase vía nodos de workflow con variables de plantilla no escapadas (CWE-89). Requiere privilegios altos (PR:H) para acceder al workflow, permitiendo lectura y modificación de datos en la BD.

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.
