You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: tuleap_unserialize_exec.rb
    path of file: ./repos/metasploit-framework/modules/exploits/unix/webapp
    
    the code of the file until where you have to start completion: ##

        This module exploits a PHP object injection vulnerability in Tuleap <= 7.6-4 which could be
        abused to allow authenticated users to execute arbitrary code with the permissions of the
        web server. The dangerous unserialize() call exists in the 'src/www/project/register.php'
        file. The exploit abuses the destructor method from the Jabbex class in order to reach a
        call_user_func_array() call in the Jabber class and call the fetchPostActions() method from
        the Transition_PostAction_FieldFactory class to execute PHP code through an eval() call. In
        order to work, the target must have the 'sys_create_project_in_one_step' option disabled.
