Vulnerability Overview
The Flexible PDF Coupons – Gift Cards & Vouchers for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.14.11. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to perform an unauthorized action.
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 interaction from a victim user.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Flexible PDF Coupons <= 1.14.11 takes an account at Contributor level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Flexible PDF Coupons the fix is 1.14.12: builds <= 1.14.11 are affected, anything from 1.14.12 onward is not.
Remediation
Update to version 1.14.12, 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: Flexible PDF Coupons 1.14.12 closes this, and updating the plugin is the step that ends it.
