WP Socializer – Simple & Easy Social Media Share Icons <= 7.2 - Authenticated (Administrator+) Stored Cross-Site Scripting

The WP Socializer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘misc_additional_css’ parameter in versions up to, and including, 7.2 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.
