Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Tickera WordPress plugin before 3.6.0.4 does not correctly verify the integrity of incoming payment notifications, and the validated signature does not cover the order or the amount, allowing unauthenticated attackers to forge a payment confirmation and mark arbitrary orders as paid without paying.
