Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Eventin WordPress plugin before 4.1.19 does not properly restrict which changes a guest checkout token is allowed to authorise on an order, allowing unauthenticated users to mark their own unpaid order as completed and be issued a valid paid ticket with no payment taken.
