Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

IA-2 Identification and Authentication (Organizational Users) good match

prevent

Mandates unique identification and authentication of users prior to granting access, directly addressing the plugin's failure to verify identity before logging in as an admin via order ID.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for logical access, preventing unauthenticated attackers from bypassing authentication to gain administrator privileges using order IDs.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of software flaws like this authentication bypass in the Simpler Checkout plugin.

Why these techniques?

Authentication bypass in public-facing WordPress plugin enables remote unauthenticated admin login via valid accounts (order ID abuse).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

The Simpler Checkout plugin for WordPress is vulnerable to Authentication Bypass in versions 0.7.0 to 1.1.9. This is due to the plugin not properly verifying a user's identity prior to logging them in as an admin through the simplerwc_woocommerce_order_created() function.…

This makes it possible for unauthenticated attackers to log in as other users based on their order ID, which can be an administrator if a site admin has placed a test order.

Deeper analysisAI

CVE-2025-7642 is an authentication bypass vulnerability (CWE-288) in the Simpler Checkout plugin for WordPress, affecting versions 0.7.0 through 1.1.9. The flaw occurs because the plugin does not properly verify a user's identity prior to logging them in as an admin via the simplerwc_woocommerce_order_created() function, published on 2025-08-23 with a CVSS 3.1 score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no privileges or user interaction required. By obtaining an order ID—such as from a test order placed by a site administrator—they can log in as any user associated with that order, potentially gaining administrator access and full control over the site.

Advisories referenced include the plugin's source code at hooks.php line 7 in version 1.1.9 on the WordPress plugin trac and a Wordfence threat intelligence report (ID 02cf0e1a-bd12-44b1-9bc5-1a5ec332b000), which detail the vulnerability for mitigation guidance.
