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

The divi-booster WordPress plugin before 5.0.2 does not have authorization and CSRF checks in one of its fixing function, allowing unauthenticated users to modify stored divi-booster WordPress plugin before 5.0.2 options. Furthermore, due to the use of unserialize() on the data, this could be further exploited when combined with a PHP gadget chain to achieve PHP Object Injection
