fastify-swagger-ui is a Fastify plugin for serving Swagger UI. Prior to 2.1.0, the default configuration of @fastify/swagger-ui without baseDir set will lead to all files in the modules directory being exposed via http routes served by the module. The vulnerability is fixed in v2.1.0. Setting the baseDir option can also work around this vulnerability.
The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.
| Name | Vendor | Start Version | End Version |

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
