Technical details

The Tickera plugin for WordPress is vulnerable to a generic SQL injection vulnerability due to insufficient escaping of the 'tc_event_filter' parameter and a lack of proper SQL query preparation. The flaw exists within the 'tc_tickets_instances' admin list screen functionality. An authenticated attacker with 'Staff' level permissions (specifically the 'edit_tc_tickets_instances' capability) can inject malicious SQL commands to bypass intended query logic. This allows for the extraction of sensitive data from the WordPress database. The issue affects all versions up to and including 3.6.0.1.

Affected products

  • Tickera Tickera – Sell Tickets & Manage Events <= 3.6.0.1
