Budibase Server before 3.41.3 contains a server-side request forgery vulnerability in the datasource verify endpoint that allows builder-level users to supply arbitrary URLs without SSRF validation. Attackers can exploit this to leak internal CouchDB credentials by making requests to attacker-controlled servers, gaining full database access in cloud deployments.
