Description

ArcadeDB versions before 26.7.2 contain an authorization bypass vulnerability in HTTP handlers for time series, batch, Prometheus, and Grafana endpoints that fail to validate database access permissions. Attackers can access and modify databases they are not authorized to use by directly calling affected endpoints with arbitrary database parameters.
