What is CVE-2023-5334?

The WP Responsive Header Image Slider plugin for WordPress is susceptible to a Stored Cross-Site Scripting (XSS) vulnerability through its 'sp_responsiveslider' shortcode.

These malicious scripts execute when users access affected pages, potentially compromising site security and user data.
