Unauthenticated Product Fulfillment Bypass in Accept Stripe Payments WordPress Plugin

Publication date: 2026-09-05

Last updated on: 2026-09-05

Assigner: WPScan

Description
The Accept Stripe Payments WordPress plugin before 2.1.4 does not verify that the product fulfilled when a checkout is completed matches the product the authoritative payment was actually made for, checking only that the amount paid is at least the referenced product's price, allowing unauthenticated attackers who complete a genuine payment to obtain fulfilment for a different, equal- or lower-priced product than the one they paid for.

Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) flaw in the Accept Stripe Payments WordPress plugin before version 2.1.4. It allows unauthenticated attackers to receive fulfillment for a different product than the one they paid for, as long as the product's price is equal or lower than the amount paid. The plugin fails to verify that the fulfilled product matches the one associated with the payment.

Detection Guidance

Check the installed version of the Accept Stripe Payments plugin in WordPress. If it is below 2.1.4, the system is vulnerable. Use WordPress admin panel or run a command like 'wp plugin list' in the WordPress directory to verify the version.

Impact Analysis

If you use the vulnerable plugin, attackers could exploit this flaw to obtain products or services they did not pay for by making a legitimate payment for a lower-priced item. This could lead to financial losses for the website owner or service provider, as well as potential reputational damage.

Compliance Impact

This vulnerability could potentially violate compliance with GDPR or HIPAA if it leads to unauthorized access to products or services tied to personal data. For example, if an attacker exploits this flaw to obtain a product they did not pay for, it may result in improper handling of user data or transactions, which could breach data protection requirements under these regulations.

Mitigation Strategies

Update the Accept Stripe Payments plugin to version 2.1.4 or later immediately. Disable the plugin temporarily if an update is not immediately available. Review recent orders to identify any unauthorized product fulfillments.
