Budibase is an open-source low-code platform. Prior to 3.38.1, Budibase exposes a REST API for datasource management. The route PUT /api/datasources/:datasourceId is registered in the authorizedRoutes group with TABLE/READ permission. This is the same authorization level as the read endpoint (GET /api/datasources/:datasourceId). Every authenticated Budibase app user with the BASIC built-in role or higher carries TABLE/WRITE (and therefore TABLE/READ) permissions, and the datasource update controller performs no additional builder check. As a result, any authenticated non-builder app user can submit a PUT request to rewrite a datasource's config object — including the connection host, port, database credentials, or the base url of a REST datasource. Because no network-level SSRF protection is applied to SQL driver connections, redirecting a PostgreSQL/MySQL/MongoDB datasource to an internal IP address succeeds and the attacker can probe or interact with internal services on arbitrary ports. This vulnerability is fixed in 3.38.1.
