Social Media Plugin by Social Snap <= 1.3.6 - Authenticated (Admin+) Stored Cross-Site Scripting

The Social Share Buttons, Social Sharing Icons, Click to Tweet — Social Media Plugin by Social Snap plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.3.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
