Shortcodes Ultimate vulnerabilities

The WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'su_box' shortcode in all versions up to, and including, 7.4.9 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 Shortcodes Ultimate plugin for WordPress up to version 7.4.8 contains a Stored Cross-Site Scripting vulnerability via the su_carousel shortcode, due to insufficient input sanitization and output escaping in the 'su_slide_link' attachment meta field.

The Shortcodes Ultimate plugin for WordPress up to version 7.4.7 has a Stored XSS vulnerability in the 'src' attribute of the su_lightbox shortcode. Insufficient input sanitization and output escaping allow authenticated attackers with contributor-level access or higher to inject scripts.
