CVE-2026-2480 is a sibling vulnerability in the same Gn Themes WP Shortcodes Plugin, Shortcodes Ultimate advisory bundle as CVE-2026-0737. The same patched build closes every CVE in the bundle, so the remediation procedure for CVE-2026-2480 matches the primary write-up.

What is different about CVE-2026-2480?

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.

Impact is consistent with the bundle: execution of attacker-controlled JavaScript in a victim's browser. The patched build closes every code path in the advisory in one update.
