SQL Injection in MPG WordPress Plugin

Publication date: 2026-09-12

Last updated on: 2026-09-12

Assigner: Wordfence

Description
The MPG – Multiple Page Generator, Bulk Landing Pages & Programmatic SEO plugin for WordPress is vulnerable to generic SQL Injection via URL Path in all versions up to, and including, 4.2.1 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 subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is only exploitable when the [mpg_spintax] shortcode is rendered in site-wide content such as a footer or template part, as the vulnerable code path is only reached when the shortcode is active on the requested page.

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

This is a SQL Injection vulnerability in the MPG WordPress plugin up to version 4.2.1. It allows authenticated attackers with subscriber-level access or higher to inject malicious SQL queries via URL paths. The flaw exists due to insufficient input escaping and lack of proper SQL query preparation.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the MPG plugin for the presence of the [mpg_spintax] shortcode in site-wide content like footers or templates. Check for unusual database queries or errors in logs when the shortcode is active.

Impact Analysis

An attacker could exploit this to extract sensitive data from the WordPress database, such as user credentials, personal information, or other confidential data. This requires the vulnerable shortcode to be active on the page being accessed.

Compliance Impact

This vulnerability could lead to unauthorized data access, potentially violating GDPR (data protection) and HIPAA (health information privacy) by exposing sensitive user data. Compliance may be compromised if personal or protected health information is accessed.

Mitigation Strategies

Immediately update the MPG plugin to the latest version beyond 4.2.1. If an update is unavailable, disable the plugin or remove the [mpg_spintax] shortcode from site-wide content until a patch is applied.
