CVE-2026-46549Network attack vector

OAuth scope escalation via unenforced ACL restrictions

Published Jun 23, 2026 · Updated Jun 23, 2026

Incorrect authorization in NocoDB before 2026.04.1 allows remote authenticated users to exceed an OAuth token's assigned scope. The OAuth token strategy records oauth_scope and oauth_granted_resources on the request user, but the ACL middleware never checks them. A restricted token must already map to a privileged user; it can then read data allowed to that user across routes, including org-level endpoints outside its granted base.
