 "title": "WebinarIgnition – Live, Automated & Evergreen Webinar System also for WooCommerce <= 4.20.01 - Unauthenticated Sensitive Information Exposure via 'cookie' Parameter in Lead Lookup AJAX Handler",
 "description": "The WebinarIgnition plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'cookie' parameter of the webinarignition_get_qa_name_email and webinarignition_get_qa_name_email2 AJAX actions, and the 'ip' parameter of the former, in all versions up to, and including, 4.20.01. This is due to the handlers looking up a lead record by a client-supplied numeric ID or IP address without checking that the record belongs to the requester; the only check is a nonce that is printed on public webinar pages. This makes it possible for unauthenticated attackers to step through sequential lead IDs and get the names and e-mail addresses of webinar registrants.",
