CVE-2026-47382
Description
NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the connection-test endpoint opened a raw TCP socket to the user-supplied database host without resolving and range-checking the destination, so private and link-local addresses (including IPv4-mapped IPv6 forms and localhost) reached the driver. This vulnerability is fixed in 2026.05.1.
Summary dbcve.org
NocoDB's connection-test endpoint suffers from a Server-Side Request Forgery (SSRF) vulnerability where it opens raw TCP sockets to user-supplied database hosts without validating whether the destination is a private, link-local, or loopback address. This allows attackers to probe internal services via IPv4, IPv6 (including IPv4-mapped IPv6), and localhost addresses.
Mitigation
Upgrade to NocoDB version 2026.05.1 or later, which implements proper destination validation to block connections to private and link-local address ranges.
