Comments feed for a non-existent URL

[manbo]

Hello.
Normally, a comments feed has a URL like http://example.com/comments/feed/, but even if you access a non-existent URL like http://example.com/abcdefg/feed/, the XML will be displayed.
is_comment_feed() works on this unknown URL, so it's clear that a comment feed is involved.
The XML displayed when the unknown URL is accessed also contains the word Comments, so it's definitely related to a comments feed.

XML excerpt

	<title>
	Comments on: 	</title>
	<atom:link href="https://192.168.100.100/abcdefg/feed/" rel="self" type="application/rss+xml" />
	<link>https://192.168.100.100</link>

hi, @manbo , can you elaborate a bit what is the issue is here exactly?

The problem is that it doesn't return an 404error when accessing a non-existent URL.

A simple solution

add_action( 'template_redirect', function() {
        if ( is_comment_feed() && esc_url_raw( site_url().$_SERVER['REQUEST_URI'] ) !== get_feed_link( 'comments_rss2' ) ) {
                wp_die( '', '', array( 'response' => 404 ) );
        }
} );
