  script_tag(name:"insight", value:"Drupal is prone to the following vulnerabilities:

  - In some conditions, content moderation fails to check a
  users access to use certain transitions, leading to an access bypass.

  - The path module allows users with the 'administer paths' to create pretty URLs for content.
  In certain circumstances the user can enter a particular path that triggers an open redirect to a malicious url.

  - Drupal core and contributed modules frequently use a 'destination' query string parameter
  in URLs to redirect users to a new destination after completing an action on the current page.
  Under certain circumstances, malicious users can use this parameter to construct a URL that will
  trick users into being redirected to a 3rd party website, thereby exposing the users to potential
  social engineering attacks.

  - When sending email some variables were not being sanitized for shell arguments,
  which could lead to remote code execution.

  - The Contextual Links module doesn't sufficiently validate the requested contextual links.
  This vulnerability is mitigated by the fact that an attacker must have a role with the permission 'access contextual links'.");
