Sina Extension AJAX responses permit reflected XSS
Sina Extension for Elementor before 3.10.2 exposes an unauthenticated AJAX handler that reconstructs a caller-controlled request value and reflects it without safe output escaping. An attacker can place script in a crafted request and execute it in the affected site's origin when a victim follows or submits that request. The CNA record does not disclose the AJAX action, parameter or vulnerable function.
