Ticket #38709: class-wp-query.php

File class-wp-query.php, 148.1 KB (added by Khadreal, 3 years ago)
The patch suggested by @rebasaurus remove the query but doesn't resolve the issue as draft post still shows up. Forcing a limit when it's singular and sanitize the input kind of do the trick and resolve it.
