Miggo AIRoot Cause Analysis

The CORS misconfiguration vulnerability arises from the improper use of the cors middleware in the index.ts file. The middleware is used without configuring it to restrict origins, thus allowing all origins. This directly relates to the 'cors' function or method being used in the code.
