CVE-2026-67343

ArcadeDB versions before 26.7.2 fail to properly redact the cluster token in the GET /api/v1/server endpoint, allowing authenticated users to retrieve the arcadedb.ha.clusterToken value in cleartext. Attackers can use the leaked token with X-ArcadeDB-Cluster-Token and X-ArcadeDB-Forwarded-User headers to impersonate root and execute administrative actions including user creation, database operations, and server shutdown.

Summary		(es) Las versiones de ArcadeDB anteriores a la 26.7.2 no logran redactar correctamente el token del clúster en el endpoint GET /API/v1/servidor, permitiendo a los usuarios autenticados recuperar el valor arcadedb.ha.clusterToken en texto claro. Los atacantes pueden usar el token filtrado con los encabezados X-ArcadeDB-Cluster-Token y X-ArcadeDB-Forwarded-User para suplantar a root y ejecutar acciones administrativas, incluyendo la creación de usuarios, operaciones de base de datos y el apagado del servidor.
