SQL Injection in GSheetConnector WordPress Plugin

Publication date: 2026-08-01

Last updated on: 2026-08-01

Assigner: Wordfence

Description
The GSheetConnector – CF7 Google Sheets Connector with Real-Time Sync plugin for WordPress is vulnerable to generic SQL Injection via the 's' parameter in all versions up to, and including, 5.2.1 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 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. wp_unslash() strips magic-quote protection and sanitize_text_field() does not escape SQL metacharacters, leaving single quotes and other SQL metacharacters intact before the value is interpolated into the query.

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 GSheetConnector plugin for WordPress. It allows authenticated attackers with administrator access or higher to inject malicious SQL queries via the 's' parameter. The issue occurs due to insufficient input sanitization and lack of proper SQL query preparation.

Detection Guidance

This vulnerability can be detected by checking for suspicious SQL query patterns in logs or monitoring database activity for unauthorized queries. Look for requests containing the 's' parameter with SQL metacharacters like single quotes or semicolons. Use WordPress debugging tools or database query logs to identify unusual activity.

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 attacker to have administrator-level access to the site.

Compliance Impact

This vulnerability could lead to unauthorized data access, potentially violating GDPR (data protection) and HIPAA (health information privacy) requirements. Organizations may face compliance breaches if sensitive data is exposed.

Mitigation Strategies

Immediately update the GSheetConnector plugin to the latest version beyond 5.2.1. If an update is unavailable, disable the plugin temporarily. Review database access logs for signs of exploitation and revoke any unauthorized user access. Consider implementing a web application firewall to block SQL injection attempts.
