Coze Studio through 0.5.1 fails to restrict the server URL supplied when registering plugin tools, allowing authenticated users to make the backend fetch internal services. Attackers can construct plugin requests to access cloud metadata endpoints and internal services reachable only from the backend network, reading responses containing sensitive information.

A vulnerability was detected in ByteDance coze-studio up to 0.5.1. Affected by this vulnerability is the function ExecuteSQL of the file backend/domain/memory/database/service/databaseimpl.go of the component databaseTool. Performing a manipulation results in sql injection. The attack can be initiated remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
