What is CVE-2026-75850?

ArcadeDB versions prior to 26.8.1 contain a vulnerability where the system fails to bind the authenticated user within batch and time-series HTTP handlers. This oversight allows individuals with limited per-type permissions to access types they are not authorized to, effectively bypassing the fine-grained access control mechanisms (LocalBucket.checkPermissionsOnFile). Only deployments utilizing per-type or per-group ACLs are susceptible; those that depend solely on database-level access control remain secure. Ensure your systems are updated to prevent unauthorized data manipulation through these endpoints.
