What is CVE-2026-67311?

Budibase versions prior to 3.38.1 are susceptible to a server-side request forgery (SSRF) vulnerability originating from inadequate validation of HTTP redirects within the REST datasource integration. This flaw permits attackers assigned the Builder role to create a REST datasource that points to an external server. If this server responds with a redirect to an internal IP address, it can exploit the system’s IP blacklist protections, thereby gaining unauthorized access to sensitive cloud metadata endpoints and internal services.
