Advisory
Source description from Wordfence Intelligence, credited to Vinay Varma Mudunuri, Krishna Harsha Kondaveeti.
The VR Calendar plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.2.2 via the handleCommands() function that accepts user supplied input via the 'vrc_cmd' parameter that is passed to call_user_func(). This allows unauthenticated attackers to execute code on the server.
