Vulnerability Description
Version 3.3.23 of the Sassy Social Share WordPress plugin is vulnerable to PHP Object Injection via the wp_ajax_heateor_sss_import_config AJAX action due to deserialization of unvalidated user supplied inputs via the import_config function found in the ~/admin/class-sassy-social-share-admin.php file.
