White Label < 2.9.1 - Cross-Site Request Forgery via white_label_reset_wl_admins

Description The White Label plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.9.0. This is due to missing or incorrect nonce validation on the white_label_reset_wl_admins function. This makes it possible for unauthenticated attackers to reset plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
