The CVE-2025-14070 vulnerability resides in the Reviewify plugin for WooCommerce, a WordPress extension that facilitates review-based discounts and media reviews. The core issue is a missing authorization check on the 'send_test_email' AJAX action, which is accessible to authenticated users with Contributor-level privileges or higher. This missing capability check (CWE-862) allows these users to invoke the AJAX action to create arbitrary discount coupons without proper permissions. Since Contributors typically cannot manage coupons, this represents a privilege escalation within the plugin's context. The vulnerability affects all versions up to and including 1.0.6. Exploitation requires no user interaction beyond logging in with a Contributor or higher account, and the attack can be performed remotely over the network. The impact is primarily on integrity, as attackers can manipulate coupon data to cause unauthorized financial discounts, potentially leading to revenue loss for WooCommerce store owners. The CVSS 3.1 score of 7.5 (High) reflects the network attack vector, low attack complexity, no privileges required beyond Contributor access, no user interaction, and a significant integrity impact. No patches or official fixes are currently linked, and no known exploits have been reported in the wild. However, the vulnerability's nature suggests it could be exploited by malicious insiders or compromised accounts to generate fraudulent discounts.

For European organizations operating WooCommerce-based e-commerce platforms with the Reviewify plugin installed, this vulnerability poses a significant risk of financial loss through unauthorized coupon creation. Attackers with low-level authenticated access can generate arbitrary discounts, undermining revenue and potentially damaging customer trust if exploited at scale. The integrity of pricing and discount mechanisms is compromised, which could also affect accounting and inventory management systems connected to WooCommerce. Additionally, exploitation could facilitate further attacks by incentivizing fraudulent purchases or enabling social engineering scams using manipulated discounts. Given the widespread use of WordPress and WooCommerce in Europe, especially in countries with mature e-commerce markets, the threat could impact a broad range of small to medium-sized enterprises reliant on online sales. The absence of user interaction and the low privilege requirement increase the likelihood of exploitation once attackers gain Contributor-level access, which can be obtained through phishing or other credential compromise methods.

1. Immediately restrict Contributor and other low-privilege user roles from accessing or interacting with the Reviewify plugin functionalities until a patch is available. 2. Monitor and audit coupon creation logs within WooCommerce to detect unusual or unauthorized discount generation activities. 3. Implement strict role-based access control (RBAC) policies, ensuring that only trusted users have Contributor or higher roles. 4. Employ multi-factor authentication (MFA) for all WordPress user accounts to reduce the risk of account compromise. 5. Regularly update the Reviewify plugin as soon as the vendor releases a patch addressing this vulnerability. 6. Consider temporarily disabling the Reviewify plugin if it is not critical to business operations until a fix is applied. 7. Use web application firewalls (WAFs) with custom rules to detect and block suspicious AJAX requests targeting the 'send_test_email' action. 8. Educate staff on phishing and credential security to prevent unauthorized access to Contributor accounts. 9. Review and tighten WordPress security configurations, including limiting plugin installation and updates to administrators only.
