CVE-2025-7642: Simplercheckout Simpler Checkout

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
