Cookie scoped to parent domain
Description: Cookie scoped to parent domain
Remediation: Cookie scoped to parent domain
By default, cookies are scoped to the issuing domain, and on IE/Edge to subdomains. If you remove the explicit domain attribute from your Set-cookie directive, then the cookie will have this default scope, which is safe and appropriate in most situations. If you particularly need a cookie to be accessible by a parent domain, then you should thoroughly review the security of the applications residing on that domain and its subdomains, and confirm that you are willing to trust the people and systems that support those applications.
