Vulnerability Overview

The Better Payment – Instant Payments, Donations, Fundraising with Subscriptions & More plugin for WordPress is vulnerable to a business logic flaw in all versions up to, and including, 2.2.0. This makes it possible for unauthenticated attackers to alter input quantities.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-1284: Improper Validation of Specified Quantity in Input

The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.

Remediation

Update to version 2.2.1, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Better Payment 2.2.1 closes this, and updating the plugin is the step that ends it.
