CVE-2025-7642
At a glance
CVE-2025-7642 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the Simpler Checkout WordPress plugin, affecting versions 0.7.0 – 1.1.13. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.2.0; sites on affected versions should update now. Disclosed August 2025, reported by kr0d.
Vulnerability Overview
The Simpler Checkout plugin for WordPress is vulnerable to Authentication Bypass in versions 0.7.0 to 1.1.13. 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.
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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-288: Authentication Bypass Using an Alternate Path or Channel
Simpler Checkout 0.7.0 – 1.1.13 carries this weakness at simplerwc_woocommerce_order_created(), and reaching it takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.
The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For Simpler Checkout the fix is 1.2.0: builds 0.7.0 – 1.1.13 are affected, anything from 1.2.0 onward is not.
Remediation
Update to version 1.2.0, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Simpler Checkout 1.2.0 closes this, and updating the plugin is the step that ends it.
