Summary
NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, the OAuth token strategy attached oauth_scope and oauth_granted_resources to the request user, but the ACL middleware never consulted either. An OAuth token issued with a restricted scope (e.g. MCP-only) therefore inherited the full permissions of the underlying user across all routes; the granted_resources.base_id restriction was bypassed on org-level endpoints that don't populate req.context.base_id. This vulnerability is fixed in 2026.04.1.
