Published:November 13, 2026
Updated:November 14, 2026
NocoDB before 2026.08.1 contains an authentication bypass vulnerability in oauth-token.service.ts that treats PKCE as a substitute for confidential client authentication, skipping client secret verification when omitted. Attackers holding a captured authorization code and PKCE verifier can mint access tokens and 60-day refresh tokens for a confidential client without knowing its secret.
