Advisory
Source description from Wordfence Intelligence, credited to Kévin Mosbahi (Mika).
The Shared Files WordPress plugin before 1.6.61 does not sanitise and escape the Download Counter Text settings, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed
