What is CVE-2026-15761?

The Tickera – Sell Tickets & Manage Events plugin for WordPress has a vulnerability that allows authenticated attackers to perform SQL injection through the 'tc_event_filter' parameter. This issue arises from inadequate parameter escaping and unsatisfactory preparation of the SQL query structure. Attackers with staff-level access can inject malicious SQL queries to retrieve sensitive information from the database. The flaw is accessible to users in the custom Staff role, which possesses capabilities to modify ticket instances on the admin screen, thereby increasing the risk of data exposure.

Affected Version(s)

Tickera – Sell Tickets & Manage Events 0 <= 3.6.0.1
