SQL Injection in SEO Booster WordPress Plugin

Publication date: 2026-07-16

Last updated on: 2026-07-16

Assigner: Wordfence

Description
The SEO Booster plugin for WordPress is vulnerable to generic SQL Injection via the 'sort_field' parameter in all versions up to, and including, 7.3.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

The SEO Booster plugin for WordPress has a SQL Injection vulnerability in versions up to 7.3.1. The 'sort_field' parameter does not properly escape user input, allowing authenticated attackers with admin access to inject malicious SQL queries. This can lead to unauthorized extraction of sensitive database information.

Impact Analysis

If you use the affected SEO Booster plugin, an attacker with admin access could steal sensitive data from your WordPress database, such as user credentials, personal information, or other confidential content.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR and HIPAA requirements for protecting personal and health information. Organizations may face compliance penalties if exploited.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the SEO Booster plugin versions up to 7.3.1. Check for unusual SQL queries or database access patterns, especially those involving the 'sort_field' parameter. Review server logs for suspicious input in requests targeting the plugin.

Mitigation Strategies

Immediately update the SEO Booster plugin to the latest version beyond 7.3.1. If an update is unavailable, disable or remove the plugin. Restrict administrator-level access to trusted users only and monitor database activity for unauthorized queries.
