Proposed remediation: add Secure and HTTPOnly flags for cookies.

It could be like this:
document.cookie = tprh=${tprh};path=/;Secure;HttpOnly;;

Screenshot:

Impact

Secure: This flag indicates that the cookie should only be sent over secure HTTPS connections. Without this flag, the cookie will be sent over both HTTP and HTTPS connections, which could expose it to interception or tampering if the connection is not secure.
HttpOnly: This flag prevents the cookie from being accessed by client-side JavaScript. It helps mitigate certain types of attacks, such as cross-site scripting (XSS), by preventing malicious scripts from accessing the cookie's value.
