CVE-2026-2480

Description

The WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'max_width' attribute of the `su_box` shortcode in all versions up to, and including, 7.4.10 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.
