What fixes it

  • 2.0.6Easy PayPal & Stripe Buy Now ButtonCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The Easy PayPal & Stripe Buy Now Button WordPress plugin before 2.0.6 does not derive the payment amount on the server, taking it from a client-supplied field, so an unauthenticated attacker sets an arbitrary lower price for a purchase.
