WordPress · Events Manager · CVE-2026-15023
**Name of the Vulnerable Software and Affected Versions**
The Events Manager – Calendar, Bookings, Tickets, and more! versions prior to 7.4.1
**Description**
An issue exists where authenticated attackers with contributor-level access and above can perform a second-order SQL injection. This occurs when an attacker first stores SQL metacharacters in a custom meta key through the standard add-meta flow. The injection is then triggered by invoking the `event duplicate` or `location duplicate` actions, which retrieve the stored meta keys via the `get post meta()` function and unsafely concatenate them into an INSERT query. This flaw is caused by insufficient escaping of the `meta key` parameter and a lack of proper preparation of the SQL query, allowing the extraction of sensitive information from the database.
**Recommendations**
Update to version 7.4.1 or later.
