Name of the Vulnerable Software and Affected Versions WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress versions up to, and including, 5.13.3

Description The issue is related to Stored Cross-Site Scripting via the plugin's su meta shortcode combined with post meta data due to insufficient input sanitization and output escaping on user supplied meta values. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 5.13.3, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the su meta shortcode for users with contributor-level and above permissions to minimize the risk of exploitation.
