Javo Spot theme for WordPress before 3.0.0 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files via the fn parameter of the jvfrmspotgetjson AJAX action. Attackers can send GET requests to /wp-admin/admin-ajax.php with fn set to ../../wp-config.php to retrieve database credentials and secret keys. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
