The CORS middleware allows for insecure configurations that could potentially expose the application to multiple CORS-related vulnerabilities. Specifically, it allows setting the Access-Control-Allow-Origin header to a wildcard (“*”) while also having the Access-Control-Allow-Credentials set to true, which goes against recommended security best practices.
