The CVE-2025-14070 vulnerability is a missing authorization (CWE-862) flaw in the Reviewify plugin for WordPress, which integrates with WooCommerce to provide review-based discounts and media uploads. The vulnerability arises because the 'send_test_email' AJAX action lacks proper capability checks, allowing any authenticated user with Contributor-level permissions or higher to invoke this action without restriction. Since Contributors can normally submit content but not manage coupons, this missing check escalates their privileges, enabling them to create arbitrary discount coupons in WooCommerce. These coupons can be used to reduce prices fraudulently, causing direct financial losses to the store owners. The vulnerability affects all versions up to 1.0.6 of Reviewify. The CVSS 3.1 score is 7.5 (high), reflecting network attack vector, low attack complexity, no privileges required beyond Contributor, no user interaction, and high impact on integrity (unauthorized coupon creation). The flaw does not impact confidentiality or availability directly but compromises the integrity of the e-commerce pricing and discount system. No patches or official fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved in December 2025 and published in January 2026. Given the widespread use of WooCommerce and the popularity of review-based discount plugins, this vulnerability poses a significant risk to online stores using Reviewify.

For European organizations operating WooCommerce-based e-commerce platforms, this vulnerability can lead to unauthorized financial losses through fraudulent coupon creation. Attackers with Contributor-level access—often granted to content creators or less-privileged users—can exploit this flaw to generate arbitrary discounts, undermining revenue and potentially damaging customer trust. The integrity of pricing and promotional mechanisms is compromised, which can also affect accounting and inventory management systems. Retailers in Europe relying on Reviewify for incentivizing reviews may face direct monetary losses and reputational damage. Additionally, if exploited at scale, it could disrupt promotional campaigns and lead to increased operational costs due to the need for manual review and remediation. The vulnerability does not directly expose customer data but could indirectly affect customer experience and trust. European GDPR regulations emphasize data integrity and security, so exploitation might also raise compliance concerns if financial fraud impacts customer transactions or data.

Immediate mitigation steps include restricting access to the 'send_test_email' AJAX action by implementing proper capability checks to ensure only authorized roles (e.g., administrators) can invoke it. Store administrators should audit user roles and permissions, limiting Contributor-level access strictly to trusted users. Monitoring WooCommerce coupon creation logs for unusual or unexpected coupons can help detect exploitation attempts early. Until an official patch is released by xfinitysoft, consider disabling the Reviewify plugin or replacing it with alternative review discount plugins that have proper authorization controls. Applying a Web Application Firewall (WAF) with custom rules to block unauthorized AJAX requests targeting this action can provide temporary protection. Regularly update WordPress, WooCommerce, and all plugins to their latest versions once patches become available. Educate content contributors about the risk and encourage reporting of suspicious activity. Finally, implement multi-factor authentication (MFA) for all user accounts to reduce the risk of compromised credentials being used to exploit this vulnerability.
