SQL Injection in Unlimited Elements For Elementor Plugin

Publication date: 2026-09-11

Last updated on: 2026-09-11

Assigner: Wordfence

Description
The Unlimited Elements For Elementor plugin for WordPress is vulnerable to SQL Injection via the 'addontype' parameter in versions up to, and including, 2.0.16. This is due to insufficient escaping on the user-supplied parameter and the lack of sufficient preparation on the existing SQL query in the getWhereString() function; when the parameter is supplied as an array, element zero is used verbatim as the SQL comparison operator and concatenated into the WHERE clause without sanitization, while normalizeAjaxInputData() strips WordPress's magic_quotes protection from the value. 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 is a SQL Injection vulnerability in the Unlimited Elements For Elementor WordPress plugin. It allows unauthenticated attackers to inject malicious SQL queries via the 'addontype' parameter. The issue occurs because user input is not properly escaped and SQL queries are not prepared safely. When the parameter is an array, the first element is used directly as a SQL operator without sanitization, enabling attackers to manipulate database queries and extract sensitive information.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the Unlimited Elements For Elementor plugin version 2.0.16 or earlier. Check for unusual SQL query patterns or unauthorized database access logs. No specific commands are provided in the context.

Impact Analysis

If you use the Unlimited Elements For Elementor plugin in versions up to 2.0.16, attackers could exploit this to access sensitive data from your WordPress database. This includes user credentials, personal information, or other confidential data stored in the site. The attack requires no authentication and can be performed remotely, making it particularly dangerous.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection. Organizations may face legal penalties, fines, or reputational damage if such a breach occurs due to inadequate security measures. Compliance with these regulations often requires protecting against SQL injection vulnerabilities.

Mitigation Strategies

Immediately update the Unlimited Elements For Elementor plugin to the latest version. If an update is unavailable, consider disabling the plugin until a patch is released. Review database access logs for suspicious activity.
