CVE-2025-10586: WordPress Community Events SQLi Flaw

CVE-2025-10586 Overview

The Community Events plugin for WordPress contains a critical SQL Injection vulnerability in the event_venue parameter affecting all versions up to and including 1.5.1. The vulnerability stems from insufficient escaping of user-supplied input and lack of proper preparation on SQL queries, allowing authenticated attackers with Subscriber-level access or higher to inject malicious SQL commands and extract sensitive information from the WordPress database.

Critical Impact
Authenticated attackers can leverage this SQL Injection flaw to extract sensitive data from the WordPress database, potentially compromising user credentials, personal information, and other critical site data.

Affected Products

Community Events plugin for WordPress versions up to and including 1.5.1
WordPress installations using vulnerable Community Events plugin versions
Any WordPress site with authenticated users (Subscriber-level or above) running affected plugin versions

Technical Details for CVE-2025-10586

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) affects the Community Events plugin for WordPress, specifically in how the plugin handles the event_venue parameter. The vulnerability allows authenticated users with minimal privileges (Subscriber-level) to manipulate database queries by injecting malicious SQL code through improperly sanitized input fields.

SQL Injection vulnerabilities of this nature occur when user-controlled input is incorporated directly into SQL queries without proper parameterization or escaping. In this case, the event_venue parameter accepts user input that is subsequently used in database operations without adequate security measures, enabling attackers to append additional SQL statements to existing queries.

The network-based attack vector means exploitation can occur remotely without requiring user interaction. Since the attack only requires Subscriber-level access—the lowest authenticated role in WordPress—the barrier to exploitation is relatively low for any WordPress site with open registration enabled.

Root Cause

The root cause of this vulnerability is twofold: insufficient escaping of the user-supplied event_venue parameter and lack of prepared statements in the existing SQL query construction. WordPress provides the $wpdb->prepare() method specifically to prevent SQL injection by properly escaping and parameterizing queries, but the vulnerable code failed to implement this security control.

When the event_venue parameter value is passed directly into SQL query strings without sanitization, special SQL characters and keywords are interpreted as part of the query syntax rather than as literal data values.

Attack Vector

An authenticated attacker with at least Subscriber-level access can exploit this vulnerability by submitting specially crafted SQL payloads through the event_venue parameter. The injected SQL commands are appended to the legitimate query and executed with the same database privileges as the WordPress application.

The attack flow involves:

Authenticating to the WordPress site with a Subscriber or higher-level account
Locating the vulnerable functionality that processes the event_venue parameter
Crafting SQL injection payloads designed to extract database contents
Submitting the malicious input through the vulnerable parameter
Receiving sensitive database information in the application's response

Technical details and code analysis are available in the WordPress Plugin Code Review and the Wordfence Vulnerability Report.

Detection Methods for CVE-2025-10586

Indicators of Compromise

Unusual database queries in WordPress logs containing SQL keywords like UNION, SELECT, or -- in the event_venue parameter
Unexpected or high-volume requests to Community Events plugin endpoints from authenticated users
Database query errors logged in WordPress debug logs indicating malformed SQL syntax
Evidence of data exfiltration or unauthorized database access in server logs

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in POST/GET parameters
Enable WordPress debug logging and monitor for database query errors related to the Community Events plugin
Deploy endpoint detection solutions to identify suspicious database query patterns and data exfiltration attempts
Monitor authentication logs for Subscriber-level accounts making unusual requests to event management functions

Monitoring Recommendations

Configure database audit logging to track queries executed against the WordPress database
Set up alerts for failed or malformed SQL queries originating from the Community Events plugin
Monitor network traffic for large data transfers that could indicate database exfiltration
Review access logs for patterns consistent with automated SQL injection testing tools

How to Mitigate CVE-2025-10586

Immediate Actions Required

Update the Community Events plugin to the latest patched version immediately
Review WordPress user accounts and remove or disable unnecessary Subscriber-level accounts
Audit database access logs for evidence of prior exploitation attempts
Consider temporarily disabling the Community Events plugin if an update cannot be applied immediately

Patch Information

A security patch addressing this vulnerability is available. Administrators should update to the latest version of the Community Events plugin via the WordPress admin dashboard or by downloading the updated plugin from the WordPress Plugin Directory. The specific code changes can be reviewed in the WordPress Plugin Change Log.

Workarounds

Disable user registration on WordPress sites to prevent new Subscriber accounts from being created
Implement additional WAF rules to filter SQL injection patterns in requests to the Community Events plugin
Restrict access to event creation and management features to Administrator-level users only
Consider using a security plugin that provides virtual patching capabilities for known vulnerabilities

bash

# Disable user registration via wp-config.php
# Add the following line to your WordPress configuration
define('WP_ALLOW_SIGNUP', false);

# Alternatively, disable via WP-CLI
