Because Wordfence thinks CP is an old version of WP, it sees the new security files included with CP 1.1.0 as a high severity issue. The solution (or workaround) is to tell Wordfence to ‘Ignore’ the files.
High Severity Problems:
- Unknown file in WordPress core: wp-admin/network/security.php
- Unknown file in WordPress core: wp-admin/security.php
