SQL Injection in EventON WordPress Plugin

Publication date: 2026-06-30

Last updated on: 2026-06-30

Assigner: Wordfence

Description
The EventON - WordPress Virtual Event Calendar Plugin plugin for WordPress (full) is vulnerable to SQL Injection via the WordPress 'search' parameter in versions up to, and including, 5.0.11 due to insufficient escaping on the user supplied parameter and lack of 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, granted the "Enable additional search queries" setting is enabled and at least one published event exists.

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

The EventON - WordPress Virtual Event Calendar Plugin is vulnerable to SQL Injection via the WordPress 'search' parameter in versions up to and including 5.0.11.

This vulnerability occurs because the plugin does not properly escape user-supplied input and fails to prepare the SQL query correctly.

As a result, unauthenticated attackers can append additional SQL queries to existing ones, potentially extracting sensitive information from the database.

This exploit is possible only if the 'Enable additional search queries' setting is enabled and there is at least one published event.

Impact Analysis

This vulnerability can have severe impacts including unauthorized access to sensitive data stored in the database.

Because the vulnerability allows unauthenticated attackers to execute arbitrary SQL queries, it can lead to data disclosure, data modification, or even complete compromise of the affected system.

The CVSS score of 9.8 indicates a critical severity with high impact on confidentiality, integrity, and availability.

Mitigation Strategies

The vulnerability exists in EventON WordPress Virtual Event Calendar Plugin versions up to and including 5.0.11. To mitigate this vulnerability, you should immediately update the plugin to a version later than 5.0.11 where the issue is fixed.

Additionally, if possible, disable the "Enable additional search queries" setting until the plugin is updated, as this setting enables the SQL injection attack vector.

Ensure that at least one published event is not exposing sensitive data during this period.
