Descripción técnica

ArcadeDB versions before 26.7.3 contain an information disclosure vulnerability in the MCP get_server_settings tool that leaks the arcadedb.ha.clusterToken in cleartext. Attackers with MCP access can retrieve the cluster token and use it with X-ArcadeDB-Cluster-Token and X-ArcadeDB-Forwarded-User headers to impersonate root and achieve full server compromise.
