## Overview

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.
