  "summary": "Insecure CORS Configuration allowing wildcard origin with credentials in github.com/gofiber/fiber/v2",
  "details": "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.",
