CVE-2026-56230

Estado: AplazadaAlta (8.7)—

Capgo before 12.128.2 contains a broken object level authorization vulnerability in middlewareKey() that accepts the client-controlled x-limited-key-id header without validating ownership, allowing authenticated users to adopt cross-tenant limited keys. Attackers can supply another tenant's limited key ID to bypass authorization checks and access unauthorized cross-tenant resources across multiple API endpoints.

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 en autorización a nivel de objeto en aplicación web (CWE-639). Usuario autenticado (PR:L) en red remota explota validación insuficiente del header x-limited-key-id para suplantarse con claves de otros tenants (T1078.004) y acceder a recursos no autorizados (T1552.007).

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.
