Advisory
Source description from Wordfence Intelligence, credited to Van Lyubov.
The ARMember – Membership Plugin, Content Restriction, Member Levels, User Profile & User signup plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.0.23 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
