The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'formData[id]' Parameter in all versions up to, and including, 2.0.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The front-end AJAX handler is registered on the public 'wp' action with no nonce, capability, or referer check, and the raw attacker-controlled id value is interpolated verbatim into an exception message that is echoed back without escaping; when the response is served as text/html rather than application/json, the browser parses the injected markup.

The Unlimited Elements For Elementor WordPress plugin before 2.0.11 does not sanitize or escape Google review content fetched from the Serp API before rendering it in the Google Reviews widget output, allowing unauthenticated attackers who submit a malicious review on the targeted business's Google listing to deliver Stored XSS to any visitor (including administrators) of any WP page displaying that Place ID's reviews.
