ArcadeDB (com.arcadedb:arcadedb-server) versions <= 26.7.3 contain an insecure direct object reference (IDOR) vulnerability in the Raft cluster-info endpoints (GetClusterHandler and PostBootstrapStateHandler), which authenticate but do not authorize access. On an ArcadeDB HA cluster (only reachable when arcadedb.ha.enabled is set and the ha-raft module is loaded), any authenticated user — including one granted access to only one database or none — can enumerate the full server database registry and retrieve per-database metadata such as database names, last transaction IDs, bootstrap fingerprints, and peer/leader cluster topology, resulting in cross-database information disclosure. Fixed in 26.8.1.
