Official description

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, two concurrent token-exchange requests using the same OAuth authorization code could each mint a distinct valid (access_token, refresh_token) pair, breaking the single-use guarantee that PKCE relies on. This vulnerability is fixed in 2026.05.1.
