## Technical details

The vulnerability is a generic SQL Injection in the [mpg_spintax] shortcode handling, caused by insufficient escaping of user-supplied URL parameters and lack of prepared statement usage in SQL query construction. The attack requires an authenticated user with subscriber-level privileges or above, and only triggers when the vulnerable shortcode is active and rendered in site-wide content such as footers or template parts. An attacker can append arbitrary SQL queries to extract sensitive data from the WordPress database. Patched versions beyond 4.2.1 should address the escaping and query preparation issues.
