Name of the Vulnerable Software and Affected Versions: Envira Gallery Lite versions prior to 1.8.3.3

Description: A stored cross-site scripting (XSS) issue allows remote attackers to inject arbitrary JavaScript/HTML code via a POST "/wp-admin/admin-ajax.php" request with the meta[title] parameter.

Recommendations: For Envira Gallery Lite versions prior to 1.8.3.3, update to version 1.8.3.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/wp-admin/admin-ajax.php" endpoint to minimize the risk of exploitation. Avoid using the meta[title] parameter in the affected API endpoint until the issue is resolved.
