CVE-2025-39496 is a critical SQL Injection vulnerability identified in the WBW WooBeWoo Product Filter Pro plugin for WordPress. This vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing an unauthenticated attacker to inject malicious SQL code. The affected versions are those prior to 2.9.6, though the exact range is not specified. The vulnerability has a CVSS 3.1 base score of 9.3, indicating a critical severity level. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L) shows that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality with a high impact, while integrity is not affected and availability impact is low. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. Technically, the flaw allows attackers to craft specially designed requests that manipulate SQL queries executed by the plugin, potentially exposing sensitive data stored in the backend database. Although no known exploits are reported in the wild yet, the ease of exploitation and the critical nature of the vulnerability make it a significant threat. The plugin is used to filter products in WooCommerce stores, which are common in e-commerce websites built on WordPress. Exploitation could lead to unauthorized disclosure of customer data, product information, or other sensitive business data stored in the database, posing a serious risk to affected organizations.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the WooBeWoo Product Filter Pro plugin, this vulnerability poses a substantial risk. Successful exploitation could lead to unauthorized access to sensitive customer data, including personal and payment information, which would violate GDPR requirements and potentially result in heavy fines and reputational damage. The confidentiality breach could undermine customer trust and lead to financial losses. Additionally, the exposure of business-critical data could affect competitive positioning. Since the vulnerability allows remote exploitation without authentication or user interaction, attackers could automate attacks at scale, increasing the risk of widespread compromise. The availability impact is low, so service disruption is less likely, but the confidentiality impact alone is severe enough to warrant urgent attention. Organizations in sectors such as retail, wholesale, and any online service relying on WooCommerce filters are particularly at risk. The vulnerability also raises compliance concerns under European data protection laws, necessitating prompt remediation and incident response preparedness.

To mitigate this vulnerability, European organizations should immediately update the WooBeWoo Product Filter Pro plugin to version 2.9.6 or later, where the issue is fixed. If an immediate update is not possible, organizations should implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the plugin's endpoints. Conduct thorough code reviews and security testing of customizations involving the plugin to ensure no additional injection vectors exist. Limit database user permissions associated with the WordPress application to the minimum necessary, preventing excessive data exposure in case of compromise. Monitor web server and application logs for suspicious query patterns or anomalous access attempts related to the plugin. Additionally, implement strict input validation and sanitization on all user-supplied data interacting with the plugin. Organizations should also review their incident response plans to quickly address any potential exploitation attempts. Finally, maintain regular backups of the website and database to enable rapid recovery if needed.
