CVE-2025-11890

Crypto Payment Gateway with Payeer for WooCommerce <= 1.0.3 - Unauthenticated Payment Bypass

Published Nov 4, 2025 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed

Description

The Crypto Payment Gateway with Payeer for WooCommerce plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 1.0.3. This is due to the plugin not properly verifying a payments status through server-side validation though the /wc-api/bp-payeer-gateway-callback endpoint. This makes it possible for unauthenticated attackers to update unpaid order statuses to paid resulting in a loss of revenue.

Analysis

Technical impact

The Crypto Payment Gateway with Payeer for WooCommerce plugin allows attackers to change the status of an unpaid order to paid without authentication. The flaw is caused by missing server‑side validation on the /wc-api/bp-payeer-gateway-callback endpoint, which lets an attacker forge a request and trigger state changes. This results in unauthorized revenue loss and violates the integrity of transaction data.

Affected Systems

WordPress sites using the beycanpress Crypto Payment Gateway with Payeer for WooCommerce plugin, versions <= 1.0.3.

Risk and Exploitability

The vulnerability has a CVSS score of 7.5, indicating high severity, while the EPSS score is below 1% suggesting exploitation is unlikely but still possible. It is not listed in CISA's KEV catalog. Based on the description, the likely attack vector is an unauthenticated HTTP request to the payment callback endpoint, allowing the attacker to modify order status server‑side.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
