Budibase versions before 3.45.0 fail to disable external JSON reference resolution in the OpenAPI/Swagger import validator, allowing authenticated builders to read arbitrary local files. Attackers with builder access can embed file:// references in OpenAPI specifications submitted to the import endpoint to exfiltrate sensitive files including environment variables containing JWT secrets, API keys, and database credentials.
