Executive brief
NocoDB, a platform that turns databases into smart spreadsheets, contained a security flaw in its data migration feature. An attacker with administrative privileges could have forced the server to access internal files or communicate with other private systems on the local network. This could lead to the exposure of sensitive internal data or unauthorized access to other services within the company's infrastructure.
Technical details
A Server-Side Request Forgery (SSRF) vulnerability exists in NocoDB's base-migration endpoint due to insufficient validation of the 'migrationUrl' parameter. Prior to version 2026.05.1, the migration worker dereferenced caller-supplied URLs without enforcing protocol restrictions or destination filtering. An attacker with the 'workspace owner' role could exploit this to abuse URI schemes (such as file: or ftp:) to read local files or probe internal HTTP destinations. The fix implemented in 2026.05.1 introduces strict protocol validation (limiting requests to http: and https:) and utilizes request-filtering-agent to block access to private IP ranges (RFC 1918), loopback, and link-local addresses.
