    [-] Vulnerability Description:
      
    User input passed through the "messageids" request parameter to /ajax/api/vb4_private/movepm is
    not properly sanitized before being used in a call to the unserialize() PHP function. This can
    be exploited by malicious users to inject arbitrary PHP objects into the application scope,
    allowing them to carry out a variety of attacks, such as executing arbitrary PHP code.
