Advisory
Source description from Wordfence Intelligence, credited to Ananda Dhakal.
The Thim Core plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.3.3. This is due to insufficient validation of user supplied input before it is executed. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary code on the server.
