description

FunnelKit Automations (wp-marketing-automations) through version 3.8.6.1 is affected by an unauthenticated PHP object injection flaw. An unauthenticated attacker may be able to inject PHP objects; the evidence indicates no authentication is required.

mitigation

Update FunnelKit Automations when a vendor-fixed release is available. Until then, reduce exposure by disabling the plugin or restricting public access to the affected WordPress site.
