CVE-2026-92804

Estado: AplazadaAlta (7.1)—

Nango through 0.70.4 fails to validate caller-supplied connection configuration values interpolated into provider token and proxy URL templates. Authenticated attackers can supply malicious configuration values to direct server requests at internal addresses or cloud metadata endpoints, potentially exfiltrating provider credentials.

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.

Autenticado explota validación ausente en URLs (CWE-918 SSRF) para dirigir peticiones a metadatos internos/nube; vector N+L+H impacto confirma acceso remoto con credenciales previas.

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.
