Creating a simple cors proxy involves piping requests, and to achieve this, I decided to utilize the pipe method with Request.js, as illustrated in the image below:

Due to my limited expertise in security, can anyone highlight potential security risks associated with the code snippet above?
Upon closer inspection, it becomes apparent that the request from your client is being directed to mysite.com (req.pipe(x);). This means that mysite.com has the ability to access your clients' cookies, as they are included in the request headers. If mysite.com is a malicious website, they could potentially use these cookies to impersonate your users on your own website. It's like handing over your computer immediately after logging into stackoverflow - the intruder wouldn't need to know your login credentials in order to carry out actions on your behalf. Sharing session cookies presents a similar security risk.
