CVE-2026-126276 · Package
NO FIX YET · SEE WHAT TO DO
NocoDB before 2026.08.1 skips client secret verification at its OAuth token endpoint when PKCE parameters are supplied. An attacker who holds a captured authorization code and PKCE verifier can mint access tokens and 60-day refresh tokens for a confidential client without its secret.

It reads this page and tells you if your code or app is affected.
Teams that self-host NocoDB and use OAuth clients registered as confidential clients are exposed, since the flaw lets an attacker with a captured authorization code and verifier skip the client secret. Installations on a version at or after 2026.08.1, or that use no OAuth integrations, are not affected by this flaw as described.
Not affected if fixed-version, no-oauth-clients
Who cares nocodb, oauth, self-hosted
2026.08.1.2026.08.1 or later.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.
