Unwanted access to the entire file system vulnerability due to a missing check in `staticFiles` HTTP handler in graphql-mesh

GraphQL Mesh is a GraphQL Federation framework and gateway for both GraphQL Federation and non-GraphQL Federation subgraphs, non-GraphQL services, such as REST and gRPC, and also databases such as MongoDB, MySQL, and PostgreSQL. Missing check vulnerability in the static file handler allows any client to access the files in the server's file system. When `staticFiles` is set in the `serve` settings in the configuration file, the following handler doesn't check if `absolutePath` is still under the directory provided as `staticFiles`. Users have two options to fix vulnerability; 1. Update `@graphql-mesh/cli` to a version higher than `0.82.21`, and if you use `@graphql-mesh/http`, update it to a version higher than `0.3.18` 2. Remove `staticFiles` option from the configuration, and use other solutions to serve static files.

对路径名的限制不恰当(路径遍历)

graphql-mesh 路径遍历漏洞

graphql-mesh是Arda TANRIKULU个人开发者的一个应用软件。 graphql-mesh存在路径遍历漏洞，该漏洞源于静态文件处理程序缺少检查，会导致任意文件读取并泄露服务器数据。
