Summary
NocoDB, an open-source no-code database platform, is affected by this flaw. An unauthenticated attacker can abuse its OAuth authorization endpoint to create large numbers of authorization code records without logging in, which could lead to database bloat and resource exhaustion on the server.
Read the original description
NocoDB 0.300.0 before 2026.08.0 contains a missing authentication vulnerability in the POST /api/v2/oauth/authorize handler that allows unauthenticated attackers to create OAuth authorization codes. Attackers can send anonymous requests with client_id, redirect_uri and approved=true to insert unbounded ownerless authorization code records, limited only by rate limiting.
What to do
Upgrade to a fixed version: 2026.08.0.
