What is CVE-2026-121736?

NocoDB versions prior to 2026.08.0 are susceptible to a missing authentication flaw in the OAuth authorization process. This vulnerability allows unauthorized attackers to create OAuth authorization codes by sending arbitrary requests with specific parameters (client_id, redirect_uri, approved=true). Attackers can exploit this flaw to generate unbounded ownerless authorization code records, constrained only by the system’s rate limiting measures. Organizations utilizing affected versions are advised to upgrade to the latest version to mitigate this risk.

Affected Version(s)

nocodb 0.300.0 < 2026.08.0
