Version 3.3.23 of the Sassy Social Share WordPress plugin is vulnerable to PHP Object Injection via the wpajaxheateorsssimportconfig AJAX action due to deserialization of unvalidated user supplied inputs via the importconfig function found in the ~/admin/class-sassy-social-share-admin.php file. This can be exploited by underprivileged authenticated users due to a missing capability check on the importconfig function.
