CVE-2019-14979: Input Validation
DISPUTED cgi-bin/webscr?cmd=cart in the WooCommerce PayPal Checkout Payment Gateway plugin 1.6.17 for WordPress allows Parameter Tampering in an amount parameter (such as amount1), as demonstrated by purchasing an item for lower than the intended price.

However, the amount is validated against the WooCommerce order total before completing the order, and if it doesn’t match then the order will be left in an “On Hold” state.
