#41224 new defect (bug)

WP strips query vars if post contains "wp-admin"

I'm running up against this rather obscure issue in the WP Query parser.

If a post name contains "wp-admin", the query vars are emptied which results in loading the front page instead of the post.

Repro steps:

  • Use built-in PHP web server to start a WP site.
  • Create a post or CPT called "test-wp-admin"
  • View the post, you will be redirected to the frontpage.

Here is the relevant code from class-wp.php

if ( isset($perma_query_vars) && strpos($_SERVER['PHP_SELF'], 'wp-admin/') !== false )
    unset( $perma_query_vars );

If you inspect $_SERVERPHP_SELF?, the resulting value is "/index.php/test-wp-admin/" which triggers the conditional.

It is not immediately clear to me why this is being done at all.

What if you instead of 'wp-admin/' would simply search for '/wp-admin/'?
