The WP Shortcode by MyThemeShop plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' parameter of the [tab] shortcode in versions up to, and including, 1.4.17. This is due to insufficient input sanitization and output escaping in the mts tabs() function, which outputs the title shortcode attribute directly into the HTML output between anchor tags without applying any escaping functions. 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.
