CVE-2024-4821

Name of the Vulnerable Software and Affected Versions WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress versions up to, and including, 7.1.6

Description The issue is related to Stored Cross-Site Scripting via the plugin's su lightbox shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations For versions up to, and including, 7.1.6, update to a version later than 7.1.6 to resolve the issue. As a temporary workaround, consider restricting access to the su lightbox shortcode for users with contributor-level access and above until a patch is available.
