What is CVE-2026-91020?

The WebToffee Gift Cards for WooCommerce plugin prior to version 1.3.1 fails to adequately validate user-provided gift card amounts on the server side. This oversight permits unauthenticated users to input arbitrary or negative amounts, sidestepping the established denominations set by the store. As a consequence, users can alter the order totals, effectively allowing them to acquire products without proper payment.

Affected Version(s)

WebToffee Gift Cards for WooCommerce 0 < 1.3.1

Exploit Proof of Concept (PoC)
