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

The Social Media Share Buttons & Social Sharing Icons WordPress plugin before 3.0.1 does not properly escape a value taken from the incoming request before outputting it in an inline JavaScript event handler, leading to Reflected Cross-Site Scripting which is triggered when a user interacts with the affected button. Exploitation requires the Social Media Share Buttons & Social Sharing Icons WordPress plugin before 3.0.1 to be running a non-default icon display configuration.
