- Nivo Slider 1.x versions prior to 3.0.0
Nivo Slider does not check permissions properly, allowing anonymous site visitors access to admin pages where they can change the module settings.
The reason is in the function nivo_slider_menu() where the property 'access callback' is set to TRUE (for 3 admin paths).
Upgrade your site to the most recent version of the Nivo Slider module. Download available on the Nivo Slider project page or on GitHub.
