SQL Injection in Events Manager WordPress Plugin

Publication date: 2026-08-25

Last updated on: 2026-08-25

Assigner: Wordfence

Description
The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to generic SQL Injection via Stored 'meta_key' via Event/Location Duplicate Action in all versions up to, and including, 7.4.0 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 contributor-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 a second-order SQL injection: an attacker first plants SQL metacharacters in a custom meta key via the standard add-meta flow (WordPress stores these verbatim in wp_postmeta), then triggers the injection by invoking the event_duplicate or location_duplicate action, which reads the stored meta keys via get_post_meta() and concatenates them unsafely into the INSERT 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 is a second-order SQL injection vulnerability in the Events Manager WordPress plugin. It allows authenticated attackers with contributor-level access or higher to inject malicious SQL queries by exploiting insufficient escaping of user-supplied parameters and lack of query preparation. The attack involves planting SQL metacharacters in a custom meta key, which later gets unsafely concatenated into an INSERT query when duplicating events or locations.

Detection Guidance

Check WordPress plugins for Events Manager versions up to 7.4.0. Look for suspicious database queries or unauthorized data access patterns in logs. Monitor for unusual meta_key values containing SQL metacharacters in wp_postmeta tables.

Impact Analysis

An attacker could extract sensitive information from the database, such as user credentials, personal data, or other confidential details. The impact depends on the site's data but could lead to data breaches, unauthorized access, or further compromise of the WordPress environment.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations may face legal penalties, reputational damage, or regulatory fines if exploited.

Mitigation Strategies

Update the Events Manager plugin to the latest version beyond 7.4.0. Remove any suspicious meta_key entries in wp_postmeta. Restrict contributor-level access to untrusted users. Review database logs for signs of exploitation.
