CVE-2025-8416 identifies a SQL Injection vulnerability in the Product Filter by WBW plugin for WordPress, versions up to and including 2.9.7. The root cause is insufficient escaping and lack of prepared statements for the 'filtersDataBackend' parameter, which is user-supplied. This flaw allows unauthenticated attackers to append arbitrary SQL commands to existing queries, enabling extraction of sensitive data from the backend database. The vulnerability does not require authentication or user interaction, increasing its exploitation potential. The CVSS 3.1 base score of 7.5 reflects a network attack vector with low complexity and no privileges required, impacting confidentiality but not integrity or availability. Although no public exploits are known, the widespread use of WordPress and this plugin in e-commerce and content management contexts raises the risk of targeted attacks. The vulnerability's CWE classification is CWE-89, indicating improper neutralization of special elements in SQL commands. The lack of official patches at the time of publication necessitates immediate defensive measures to prevent exploitation.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive customer and business data stored in WordPress databases. E-commerce sites using the Product Filter by WBW plugin could have their customer information, transaction records, and other proprietary data exposed. Data breaches could lead to regulatory penalties under GDPR, reputational damage, and financial losses. The vulnerability's unauthenticated nature means attackers can exploit it remotely without prior access, increasing the threat surface. Additionally, the extraction of sensitive data could facilitate further attacks such as identity theft, fraud, or targeted phishing campaigns. Organizations relying on WordPress for critical business functions must consider the potential operational disruption and compliance implications of this vulnerability.

1. Immediately audit all WordPress installations for the presence of the Product Filter by WBW plugin and identify versions up to 2.9.7. 2. If an official patch or updated plugin version is released, apply it without delay. 3. In the absence of a patch, restrict access to the vulnerable 'filtersDataBackend' parameter endpoint by implementing IP whitelisting or authentication controls at the web server or application firewall level. 4. Deploy a Web Application Firewall (WAF) with SQL Injection detection and prevention capabilities, tuning it to detect exploitation attempts targeting this parameter. 5. Conduct regular database and application log monitoring to identify anomalous queries or access patterns indicative of exploitation attempts. 6. Educate development and security teams about secure coding practices, emphasizing the use of parameterized queries and input validation to prevent SQL Injection. 7. Consider isolating WordPress instances and limiting database user privileges to minimize potential data exposure. 8. Prepare incident response plans specifically addressing SQL Injection attacks and data breach scenarios.
