At a glance
CVE-2026-9612 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the WhatsOrder WordPress plugin, affecting versions <= 1.0.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed June 2026, reported by Benedictus Jovan (aillesiM).
Vulnerability Overview
The WhatsOrder – Instant Checkout for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.0.1 via the yapacdev_generate_order_pdf. This makes it possible for unauthenticated attackers to extract sensitive customer PII and order details — including full name, email address, phone number, billing address, ordered items with quantities and prices, applied coupons, shipping method, and order total — from any customer's invoice by enumerating sequential order IDs. Invoice HTML files are written to the publicly accessible wp-content/uploads/whatsorder_invoices/ directory, which is created without an .htaccess deny rule or index.php guard, making every invoice directly downloadable over HTTP with no authentication check.
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.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Reaching this weakness in WhatsOrder <= 1.0.1 takes no account at all. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. No fixed build of this plugin is recorded for WhatsOrder yet, so installs running <= 1.0.1 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
