SQL Injection in wpForo Forum WordPress Plugin

Publication date: 2026-08-28

Last updated on: 2026-08-28

Assigner: Wordfence

Description
The wpForo Forum plugin for WordPress is vulnerable to SQL Injection via the 'referer' parameter in all versions up to, and including, 2.4.17. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers 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

This vulnerability is a SQL Injection flaw in the wpForo Forum plugin for WordPress up to version 2.4.17. It occurs because the 'referer' parameter is not properly escaped and SQL queries are not sufficiently prepared. Unauthenticated attackers can inject malicious SQL code to extract sensitive data from the database.

Detection Guidance

This vulnerability can be detected by checking for SQL injection attempts targeting the 'referer' parameter in the wpForo plugin. Monitor web server logs for unusual SQL syntax patterns or requests containing malicious SQL payloads. Use tools like grep to search logs for suspicious strings such as 'UNION SELECT', 'OR 1=1', or other SQL keywords.

Impact Analysis

An attacker could exploit this to steal sensitive information from your WordPress database, such as user credentials, personal data, or other confidential content. This could lead to data breaches, unauthorized access, or further attacks on your site.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR (data protection) and HIPAA (health data privacy) requirements. Organizations may face legal penalties, fines, or reputational damage if exploited.

Mitigation Strategies

Immediately update the wpForo plugin to the latest version beyond 2.4.17. If an update is not available, consider disabling the plugin temporarily until a patch is released. Review database access logs for signs of exploitation and restrict database user permissions to limit potential damage.
