NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the spreadsheet-import endpoint axiosRequestMake could be used as a generic HTTP proxy. Before the fix it was reachable unauthenticated, and its URL-extension allowlist was a regex tested against the full URL string, so URLs whose query string ended in .csv satisfies the gate even though the underlying request is for another file. This vulnerability is fixed in 2026.05.1.
