Logo Slider < 3.6.0 - Contributor+ Stored XSS in Shortcode

The plugin does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

PoC

Note: First, you need to add a Logo Slider. Exploit: [logo-slider border=‘yes’ bordercolor=‘red" onmouseover=“alert(1)”’]
