The Testimonial Carousel For Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the show_line_text and slide_button_hover_animation parameters in versions up to, and including, 10.1.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
