SQL Injection in Registrations For The Events Calendar WordPress Plugin

Publication date: 2026-07-23

Last updated on: 2026-07-23

Assigner: Wordfence

Description
The Registrations For The Events Calendar plugin for WordPress is vulnerable to SQL Injection via JSON keys in the 'standard' parameter handled by the rtec_records_edit AJAX action in versions up to and including 3.2. The handler decodes attacker-controlled JSON from $_POST['standard'] and uses the JSON array keys directly as column identifiers in the SET clause of an UPDATE statement built inside RTEC_Db_Admin::update_entry(). Only esc_sql() (mysqli_real_escape_string) is applied to the identifier; that function escapes quotes, backslashes, and a few control characters but does not escape spaces, equals signs, parentheses, or hyphens, so an attacker can break out of the identifier context and inject subqueries (terminated with a SQL comment). This makes it possible for authenticated attackers, with Contributor-level access and above who can edit the targeted event, 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 Registrations For The Events Calendar WordPress plugin. It allows authenticated attackers with Contributor-level access or higher to inject malicious SQL queries via the 'standard' parameter in the rtec_records_edit AJAX action. The plugin decodes attacker-controlled JSON and uses its keys directly as column identifiers in an UPDATE statement without proper sanitization.

Detection Guidance

This vulnerability requires authenticated access with Contributor-level permissions or higher. Detection involves checking for suspicious SQL query patterns in logs or monitoring for unauthorized database access attempts. Look for POST requests to /wp-admin/admin-ajax.php with the action parameter set to 'rtec_records_edit' and unusual JSON input in the 'standard' parameter.

Impact Analysis

An attacker could exploit this to extract sensitive data from your WordPress database, such as user credentials, personal information, or other confidential data stored in the events calendar system. They could also potentially modify or delete database entries if the injected queries allow it.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Organizations may face compliance violations, fines, or legal consequences if exploited.

Mitigation Strategies

Update the Registrations For The Events Calendar plugin to the latest version, which patches the SQL injection vulnerability. If an update is not available, consider disabling the plugin temporarily until a patch is released.
