The plugin does not escape its Image URL button setting, which could lead allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.

Add the following payload in the Universal Button > Image URL settings: " onerror=alert(/XSS/) "

The XSS will be triggered in all frontend posts
