Inline Image Upload for BBPress < 1.1.19 - Cross-Site Request Forgery via hm_bbpui_admin_page

Description The Inline Image Upload for BBPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.18. This is due to missing or incorrect nonce validation on the hm_bbpui_admin_page function. This makes it possible for unauthenticated attackers to trigger a cleanup via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
