CVE-2026-67342 is an authorization bypass vulnerability affecting ArcadeDB versions prior to 26.7.2. The flaw resides in HTTP handlers associated with the time series, batch, Prometheus, and Grafana endpoints, which fail to validate database access permissions for the database specified in requests. By directly invoking these endpoints with arbitrary database parameters, an attacker can interact with databases outside their authorized scope. The issue enables unauthorized access to and modification of database content through exposed HTTP functionality.
