CVE-2026-25318 identifies a missing authorization vulnerability in the WiserReview Product Reviews plugin developed by the Wisernotify team for WooCommerce, a widely used e-commerce platform. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions within the plugin. This misconfiguration allows an attacker to bypass authorization checks and perform actions that should be restricted, such as modifying or deleting product reviews, or potentially injecting fraudulent reviews. The affected versions include all versions up to and including 2.9. The vulnerability does not require prior authentication, increasing the risk of exploitation by remote attackers. Although no public exploits have been reported yet, the nature of the vulnerability suggests that it could be exploited to undermine the integrity and trustworthiness of product reviews, which are critical for customer decision-making and vendor reputation. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed, but the missing authorization issue is a common and serious security flaw. The plugin’s role in managing user-generated content means that exploitation could also impact availability if attackers disrupt review functionality or cause denial of service. The vulnerability was published on February 19, 2026, and no patches or mitigations have been officially released at the time of this report.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the WiserReview plugin, this vulnerability poses significant risks. Unauthorized modification or deletion of product reviews can damage customer trust, reduce sales, and harm brand reputation. Attackers could inject fake reviews to manipulate product ratings, misleading customers and potentially violating consumer protection laws. The integrity of review data is critical for compliance with EU regulations on truthful advertising and consumer rights. Additionally, disruption of review services could degrade user experience and availability of key e-commerce features. Since the vulnerability does not require authentication, it increases the attack surface and risk of automated exploitation. This could lead to widespread impact across multiple online stores, especially those that rely heavily on customer reviews for competitive advantage. The absence of known exploits currently provides a window for proactive mitigation, but the threat remains significant given the plugin’s market presence and the importance of e-commerce in Europe’s digital economy.

1. Immediately audit all WooCommerce installations for the presence of the WiserReview Product Reviews plugin and identify versions at or below 2.9. 2. Until an official patch is released, restrict access to the plugin’s administrative and review management interfaces using web application firewalls (WAFs) or IP whitelisting to limit exposure. 3. Implement strict role-based access controls within WordPress to ensure only trusted users have permissions to manage reviews. 4. Monitor logs and review data for unusual activity, such as unexpected changes or deletions of reviews, which could indicate exploitation attempts. 5. Engage with the Wisernotify team or plugin maintainers to obtain updates on patch availability and apply security updates promptly once released. 6. Consider temporarily disabling the plugin if it is not critical to business operations until a secure version is available. 7. Educate site administrators about the vulnerability and encourage vigilance against phishing or social engineering attacks that could facilitate exploitation. 8. Employ security plugins that can detect unauthorized changes to content or configurations within WordPress environments.
