multisite potential issue

On multisite wordpress sites, the path for setcookie() is set as SITECOOKIEPATH.
This could cause serious issues in cases like below:

2 multisite websites with subdirectories
https://test.com/blog1/
with user1 as Admin, user2 as Editor
https://test.com/blog1/
with user1 as Editor, user2 as Admin

When I switch user in blog1 from user1 to user2, and the access blog2, I can access the blog as Admin.
This is because setcookie() path is not set as the multisite’s path.

Instead of SITECOOKIEPATH, for multisite with subdirectories, it is safer to use

$blog_details = get_blog_details();
$SITECOOKIEPATH = $blog_details->path;
