Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Better Payment WordPress plugin before 2.3.4 does not validate the submitted payment amount server-side against the merchant's configured fixed price before building the gateway charge, allowing unauthenticated users to pay an arbitrary reduced amount for a fixed-price item.
