The Social Sharing Plugin WordPress plugin before 3.3.61 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

The Social Sharing WordPress plugin before 3.3.45 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

The Social Sharing Plugin WordPress plugin before 3.3.40 does not escape the viewed post URL before outputting it back in onclick attributes when the "Enable 'More' icon" option is enabled (which is the default setting), leading to a Reflected Cross-Site Scripting issue.

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.
