CVE-2026-67343 is a high-severity flaw (CVSS 8.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
