Advisory
Source description from Wordfence Intelligence, credited to João Pedro Soares de Alcântara.
The Masterstudy theme for WordPress is vulnerable to Local File Inclusion in versions up to 4.8.126. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other "safe" file types can be uploaded and included.
