What is CVE-2026-67343?

ArcadeDB versions prior to 26.7.2 contain a vulnerability that fails to redact the cluster token when accessed via the GET /api/v1/server endpoint. This allows authenticated users to view the sensitive arcadedb.ha.clusterToken in plaintext. With this exposed token, attackers can craft requests using the X-ArcadeDB-Cluster-Token and X-ArcadeDB-Forwarded-User headers to impersonate an administrative user, enabling them to perform critical operations like user creation, database manipulations, and server shutdown, thereby compromising the integrity and security of the system.
