Comment 1 Huzaifa S. Sidhpurwala 2016-10-20 05:20:45 UTC
This issue happens when untrusted input is unserialized.  Doing so it documented as being unsafe:

  http://php.net/manual/en/function.unserialize.php

  Do not pass untrusted user input to unserialize(). Unserialization can
  result in code being loaded and executed due to object instantiation and
  autoloading, and a malicious user may be able to exploit this. Use a safe,
  standard data interchange format such as JSON (via json_decode() and
  json_encode()) if you need to pass serialized data to the user.
