Summary
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.

Inferred packages
No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of nocodb/nocodb published their own advisory on GitHub. Reviewed sources take precedence over it.
