NocoDB before 2026.06.2 Credential Disclosure via Public OAuth Client Endpoint

NocoDB before 2026.06.2 contains an information disclosure vulnerability that allows unauthenticated attackers to retrieve full OAuth client records by querying the public client lookup route in oauth.controller.ts. Attackers who know or guess a client identifier can obtain the registration access token to modify or delete registrations, plus the bcrypt client secret hash and owner's internal identifier.
