Advisory
Source description from Wordfence Intelligence, credited to Karthik Ramakrishnan.
The Contact Form by Supsystic plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.11.0. This is due to insufficient validation of user supplied input before it is executed. This makes it possible for authenticated attackers, with administrator-level access and above, to execute arbitrary code on the server.
