WordPress Plugin Vulnerabilities
Social comments by WpDevArt < 2.5.0 - Admin+ Stored Cross-Site Scripting
Description
The plugin does not sanitise and escape its settings, allowing high privilege users such as admin to perform cross-Site Scripting attacks even when unfiltered_html is disallowed
Proof of Concept
Put the following payload in any of the plugin's text field settings (such as Title , Title font-size etc): "><svg onload=prompt(1)// Then save and reload the settings to trigger the XSS. The XSS will also trigger in pages/posts where the plugin's shortcode is embed
Affects Plugins
Fixed in version 2.5.0
