 "title": "Popularis Extra <= 1.2.10 - Cross-Site Request Forgery to Plugin Activation",
 "description": "The Popularis Extra plugin for WordPress is vulnerable to Cross-Site Request Forgery via the popularis_ajax_required_plugins_activate AJAX action in all versions up to, and including, 1.2.10, due to missing nonce validation in the ajax_required_plugins_activate() function. This makes it possible for unauthenticated attackers to activate any plugin already installed on the site through a forged request, provided they can trick a site administrator into performing an action such as clicking a link.",
