  author: random-robbie
  severity: medium
  description: |

    Successful exploitation of this vulnerability could lead to the execution of arbitrary script code in the context of the victim's browser, potentially leading to session hijacking, defacement, or theft of sensitive information.
  remediation: |
    Update to the latest version of the WordPress Visual Form Builder plugin (3.0.8) or apply the vendor-supplied patch to mitigate this vulnerability.
