Description
The Swagger UI Try-out console within the API Publisher documentation allows an external Swagger API definition URL to be loaded, overriding the existing API definitions within the Publisher portal. By exploiting this vulnerability, malicious actors can deceive users into interacting with these overwritten API definitions. This could lead to the exposure of sensitive information or the initiation of unintended requests to backend services.
