The Themify Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's themifybutton shortcode in all versions up to, and including, 2.0.9 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Themify Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'themifypostslider shortcode in all versions up to, and including, 2.0.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Themify Shortcodes WordPress plugin before 2.0.8 does not validate and escape one of its shortcode attributes, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attack.
