NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the base-migration endpoint accepted a caller-supplied URL that the migration worker dereferenced without enforcing protocol or destination, allowing scheme abuse (file:, ftp:, etc.) and probing of internal HTTP destinations.
