Description

Missing Authorization vulnerability in VillaTheme Customer Coupons for WooCommerce woo-customer-coupons allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Customer Coupons for WooCommerce: from n/a through 1.3.14.

Analysis

Technical impact

The vulnerability is a missing authorization flaw in the VillaTheme Customer Coupons for WooCommerce plugin. Incorrectly configured access control levels allow any user, authenticated or not, to trigger coupon functions that are meant to be restricted. This can enable a malicious actor to create or activate premium coupons, bypassing normal purchase restrictions and potentially inflating revenue through fraudulent use.

Affected Systems

WordPress sites that have installed the Customer Coupons for WooCommerce plugin from the initial release through 1.3.14 are affected. Site administrators should verify the installed plugin version and upgrade if necessary.

Risk and Exploitability

The CVSS base score of 4.3 indicates moderate severity. No EPSS score is available, and the vulnerability is not listed in the CISA KEV catalog, suggesting limited reported exploitation. The flaw can be exploited remotely by sending HTTP requests to the plugin’s endpoints, without the need for privileged credentials. Although the attack surface is exposed, the impact is confined to unauthorized coupon operations, but it remains a significant concern for sites relying on this plugin.

Remediation

Vendor Solution

Update the WordPress Customer Coupons for WooCommerce plugin to the latest available version (at least 1.3.15).

OpenCVE Recommended Actions

Update the plugin to version 1.3.15 or later where the access controls are corrected.
If an immediate update is not possible, restrict the plugin’s functionality to authenticated administrators only by adjusting the role‑based access settings or applying a custom code snippet that enforces stricter checks on coupon creation and activation.
Review and test the site’s role hierarchy to ensure that default user roles do not have permission to create or activate coupons through the plugin’s settings.
