Social Media Share Buttons & Social Sharing Icons < 3.0.1 - Contributor+ Stored XSS via Post Title

Description

The plugin does not escape the post title before outputting it in an inline JavaScript event handler, allowing users with the Contributor role and above to perform Stored Cross-Site Scripting attacks which are triggered when a visitor interacts with the affected button.
Exploitation requires the plugin to be running a non-default icon display configuration.
