Descriptions

The myStickymenu WordPress plugin before 2.6.5 does not adequately authorize some ajax calls, allowing any logged-in user to perform the actions.

El complemento myStickymenu de WordPress anterior a 2.6.5 no autoriza adecuadamente algunas llamadas ajax, lo que permite que cualquier usuario que haya iniciado sesión realice las acciones.

The Floating Notification Bar, Sticky Menu on Scroll, Announcement Banner, and Sticky Header for Any Theme – My Sticky Bar (formerly myStickymenu) plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the my_sticky_menu_bulks() function in all versions up to, and including, 2.6.4. This makes it possible for authenticated attackers, with subscruber-level access and above, to delete arbitrary form leads. There were several additional AJAX actions in the plugin with missing capability checks as well such as mystickymenu_admin_send_message_to_owner(), stickymenu_widget_delete(), mystickymenu_widget_status() and more that make is possible for authenticated attackers to perform unauthorized actions.
