CVE-2014-10067
Validation Bypass in paypal-ipn
paypal-ipn before 3.0.0 uses the test_ipn parameter (which is set by the PayPal IPN simulator) to determine if it should use the production PayPal site or the sandbox. With a bit of time, an attacker could craft a request using the simulator that would fool any application which does not explicitly check for test_ipn in production.

Validation Bypass in paypal-ipn
Versions 2.x.x and earlier of paypal-ipn are affected by a validation bypass vulnerability.
paypal-ipn uses the test_ipn parameter (which is set by the PayPal IPN simulator) to determine if it should use the production PayPal site or the sandbox.
A motivated attacker could craft a request string using the simulator to fool the application into entering the sandbox mode, potentially allowing purchases without valid payment.
Recommendation
Upgrade to version 3.0.0 or later.
