CVE-2025-14124: Team WordPress Plugin SQLi Vulnerability

CVE-2025-14124 Overview

CVE-2025-14124 is a SQL Injection vulnerability affecting The Team WordPress plugin versions prior to 5.0.11. The vulnerability exists due to improper sanitization and escaping of a parameter before it is used in a SQL statement. This flaw is accessible through an AJAX action available to unauthenticated users, making it particularly dangerous as no authentication is required for exploitation.

Critical Impact
Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive data from the WordPress database, including user credentials, email addresses, and potentially other confidential information stored within the site.

Affected Products

The Team WordPress plugin versions before 5.0.11

Technical Details for CVE-2025-14124

Vulnerability Analysis

This vulnerability represents a classic SQL Injection flaw in the WordPress ecosystem. The Team plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries. The vulnerable AJAX action endpoint accepts parameters from any user, including unauthenticated visitors, and passes this input directly into database queries without adequate validation or escaping.

The attack can be executed over the network without any user interaction or authentication requirements. A successful exploitation allows attackers to read sensitive data from the database, though it does not permit direct modification or destruction of data. The scope is changed, meaning the vulnerable component and the impacted component are different, allowing attackers to affect resources beyond the security scope of the vulnerable plugin.

Root Cause

The root cause of this vulnerability is inadequate input validation and improper use of database query construction. Instead of using WordPress's built-in prepared statements via $wpdb->prepare(), the vulnerable code directly concatenates user input into SQL queries. This allows attackers to inject malicious SQL syntax that modifies the intended query behavior.

Attack Vector

The attack is executed remotely via the network by sending crafted HTTP requests to the WordPress AJAX handler (admin-ajax.php). An attacker can submit specially crafted input containing SQL syntax through the vulnerable parameter. Since the AJAX action is accessible without authentication, any internet-connected attacker can target vulnerable installations.

The vulnerability manifests when user-supplied data is incorporated into SQL queries without proper sanitization. Attackers can inject SQL commands to extract database contents, enumerate tables, or access sensitive WordPress user data. For technical details on the specific exploitation methodology, refer to the WPScan Vulnerability Report.

Detection Methods for CVE-2025-14124

Indicators of Compromise

Unusual or malformed requests to admin-ajax.php containing SQL syntax characters such as single quotes, UNION statements, or comment sequences
Database query logs showing unexpected SELECT statements with UNION-based injection patterns
Anomalous web traffic patterns targeting WordPress AJAX endpoints from single IP addresses
Error logs indicating SQL syntax errors from the The Team plugin components

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to WordPress AJAX handlers
Monitor web server access logs for requests containing typical SQLi payloads targeting admin-ajax.php
Implement database query logging to identify anomalous or unauthorized SELECT statements
Use vulnerability scanners to identify WordPress installations running The Team plugin versions below 5.0.11

Monitoring Recommendations

Enable WordPress debug logging to capture plugin-related errors that may indicate exploitation attempts
Configure SIEM alerts for patterns matching SQL injection attacks against WordPress installations
Regularly audit installed plugin versions against known vulnerability databases
Monitor outbound network traffic for unusual data exfiltration patterns from web servers

How to Mitigate CVE-2025-14124

Immediate Actions Required

Update The Team WordPress plugin to version 5.0.11 or later immediately
If immediate patching is not possible, temporarily disable The Team plugin until it can be updated
Review web server logs for evidence of prior exploitation attempts
Consider implementing additional WAF rules to protect against SQL injection attacks

Patch Information

The vulnerability has been addressed in version 5.0.11 of The Team WordPress plugin. Site administrators should update the plugin through the WordPress admin dashboard or by downloading the latest version from the official WordPress plugin repository. After updating, verify the installed version is 5.0.11 or higher.

For detailed vulnerability information, see the WPScan Vulnerability Report.

Workarounds

Disable the plugin entirely until a patch can be applied
Implement WAF rules to block requests containing SQL injection patterns to WordPress AJAX endpoints
Restrict access to admin-ajax.php at the web server level if plugin functionality is not required
Use WordPress security plugins that provide SQL injection protection capabilities

bash

# Example: Block suspicious requests in .htaccess (Apache)
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (\%27)|(\')|(\-\-)|(\%23)|(#) [NC]
    RewriteRule .* - [F,L]
</IfModule>
