Message:

Grouped backports to the 5.2 branch.

• Comments: Prevent users who can not see a post from seeing comments on it.
• Shortcodes: Restrict media shortcode ajax to certain type.
• REST API: Ensure no-cache headers are sent when methods are overridden.
• REST API: Limit search_columns for users without list_users.
• Prevent unintended behavior when certain objects are unserialized.
