Budibase before 3.38.1 contains a server-side request forgery vulnerability in the REST datasource integration that fails to validate HTTP redirects against the IP blacklist. Attackers with Builder role can configure a REST datasource pointing to an external server that returns a redirect to internal IP addresses, bypassing blacklist protection to access cloud metadata endpoints and internal services.
