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. This can be exploited by underprivileged authenticated users due to a missing capability check on the import_config function.
