Advisory

Source description from Wordfence Intelligence, credited to shaman0x01.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the profile picture upload functionality in all versions up to, and including, 4.16.4 due to insufficient file type validation. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload HTML files with arbitrary web scripts that will execute whenever a user accesses the file.
