Package	Ecosystem	Affected	Fixed in
sylius/paypal-plugin	Packagist	<1.6.1 \|\| >=1.7.0, <1.7.1 \|\| >=2.0.0, <2.0.1	1.6.1, 1.7.1, 2.0.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Sylius PayPal Plugin (sylius/paypal-plugin) versions before 1.6.1, from 1.7.0 before 1.7.1, and from 2.0.0 before 2.0.1 are affected. If a customer changes item quantities in their cart after starting PayPal Checkout, PayPal is not sent the updated total, so the customer can pay less than the order value, and Sylius marks the order as fully paid. Upgrade to version 1.6.1, 1.7.1, or 2.0.1 or later; the source also describes workarounds that involve overriding several plugin classes, which are documented in the advisory.
