Advisory
Source description from Wordfence Intelligence, credited to Asif Nawaz Minhas.
The Simple Social Media Share Buttons WordPress plugin before 3.2.4 does not escape the Share Title settings before outputting it in the frontend pages or posts (depending on the settings used), allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
