No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The WP Directory Kit WordPress plugin before 1.5.7 does not sanitise and escape a parameter before using it in a SQL statement, allowing administrators to perform SQL injection attacks. On a multisite installation this lets an administrator of a single site read data belonging to the entire network, which they are not otherwise able to reach.
