CVE-2026-67343Public exploitNetwork attack vector

Root impersonation via exposed HA cluster token

Published Aug 1, 2026 · Updated Aug 1, 2026

Information disclosure in ArcadeDB before 26.7.2 allows remote authenticated users to obtain a configured HA cluster token. The GET /api/v1/server handler exports non-database settings but masks only names containing password, ignoring the hidden-setting flag on arcadedb.ha.clusterToken. Exploitation requires an explicitly configured HA_CLUSTER_TOKEN; replay with the forwarded-user header grants root administrative control, including database changes and server shutdown.
