CVE-2026-30887

Estado: AnalizadaCrítica (9.9)—

OneUptime is a solution for monitoring and managing online services. Prior to 10.0.18, OneUptime allows project members to run custom Playwright/JavaScript code via Synthetic Monitors to test websites. However, the system executes this untrusted user code inside the insecure Node.js vm module. By leveraging a standard prototype-chain escape (this.constructor.constructor), an attacker can bypass the sandbox, gain access to the underlying Node.js process object, and execute arbitrary system commands (RCE) on the oneuptime-probe container. Furthermore, because the probe holds database/cluster credentials in its environment variables, this directly leads to a complete cluster compromise. This vulnerability is fixed in 10.0.18.

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 ejecución de código en Node.js vm (CWE-94) en servicio remoto que requiere autenticación de proyecto (PR:L). Prototype-chain escape permite RCE y acceso a credenciales de entorno 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.

Sin embargo, el sistema ejecuta este código de usuario no confiable dentro del módulo vm inseguro de Node.js. Al aprovechar un escape estándar de la cadena de prototipos (this.constructor.constructor), un atacante puede eludir la sandbox, obtener acceso al objeto de proceso subyacente de Node.js y ejecutar comandos de sistema arbitrarios (RCE) en el contenedor oneuptime-probe. Además, debido a que la sonda guarda las credenciales de la base de datos/clúster en sus variables de entorno, esto conduce directamente a un compromiso completo del clúster.
