CVE-2026-126280 NocoDB before 2026.08.0 Refresh Token Reuse via Non-Atomic Rotation

9.1 criticalEPSS 0.3%

Critical (9.1) in nocodb nocodb. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.

On this page
NocoDB before 2026.08.0 contains a race condition in refresh-token rotation that allows attackers to reuse tokens because UserRefreshToken.ts never checks the affected-row count. Attackers holding a captured refresh token can present it concurrently with the legitimate user to obtain a valid authenticated session, and no reuse event is recorded.
