CVE-2026-4079 is a SQL Injection vulnerability affecting the SQL Chart Builder plugin for WordPress. This vulnerability allows unauthenticated attackers to inject malicious SQL queries, potentially leading to unauthorized access and data extraction from the database. The vulnerability impacts versions of the plugin up to 2.3.8. A patch is available in version 2.3.8.
CVE-2026-4079 in the SQL Chart Builder plugin for WordPress poses a significant security risk to websites utilizing it. This SQL Injection vulnerability allows unauthenticated attackers to manipulate existing SQL queries, potentially extracting sensitive data stored in the database. The CVSS score of 7.5 indicates a moderately high level of risk. Insufficient validation and escaping of user-supplied parameters, combined with a lack of prepared statements, facilitates exploitation. This could result in the exposure of user personal information, business data, or even complete website control.
An attacker could exploit this vulnerability by sending malicious requests to the website containing injected SQL code. This code could be inserted into existing SQL queries, allowing the attacker to access data that would normally be protected. The lack of authentication means the attacker doesn't need valid credentials to exploit the vulnerability. The success of exploitation depends on the server configuration and database permissions, but even an attacker with basic knowledge can leverage this weakness. The vulnerability is particularly concerning for websites storing personal or financial information.
