Input validation vulnerability in Slider by 10Web 1.2.56

The Slider by 10Web plugin for WordPress has a security issue where hackers can insert harmful code into the slider settings. This can happen on versions 1.2.56 and below because the plugin does not properly filter and protect the input and output of the settings. Attackers with editor or higher permissions can exploit this vulnerability on multi-site installations or if the unfiltered_html feature is turned off.
