What is CVE-2026-0738?

The WP Shortcodes Plugin, specifically the Shortcodes Ultimate plugin for WordPress, is prone to a Stored Cross-Site Scripting vulnerability through the 'su_carousel' shortcode. This issue arises from inadequate input sanitization and output escaping mechanisms in the 'su_slide_link' attachment meta field. Authenticated users with author-level permissions can exploit this flaw to inject malicious scripts into pages, leading to persistent execution of these scripts when accessed by other users. This can have serious implications for site security and user safety.
