AI-suggested
Upgrade Budibase server to version 3.45.0 or later, where this vulnerability is fixed by disabling external JSON reference resolution in the OpenAPI/Swagger import validator. No other mitigations are specified. Patch status is confirmed by the affected version range indicating the fix in 3.45.0.
Description
Budibase server versions prior to 3.45.0 contain a vulnerability in the OpenAPI/Swagger import validator that allows authenticated builder users to read arbitrary local files. This occurs because external JSON reference resolution is not disabled, enabling attackers to embed file:// references to exfiltrate sensitive information such as environment variables, JWT secrets, API keys, and database credentials.
