CVE-2026-126280 PUBLISHED

NocoDB before 2026.08.0 Refresh Token Reuse via Non-Atomic Rotation

Assigner: VulnCheck
Reserved: 10.11.2026 Published: 13.11.2026 Updated: 13.11.2026

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.
