Vulnerability in villatheme Photo Reviews for WooCommerce

[ Description ]Official description

The Photo Reviews for WooCommerce plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'wcpr_image_upload_id' parameter in all versions up to, and including, 1.2.30 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The publicly-emitted `wcpr_image_upload` nonce printed on every product review form is the only gate, and no capability, authentication, or attachment ownership check is performed, allowing the payload to be stored in comment meta — which is not subject to `wp_kses` — by any unauthenticated visitor; the XSS fires once the review is visible on the frontend.
