CVE-2025-13409: WordPress Form Vibes SQLi Vulnerability

CVE-2025-13409 Overview

The Form Vibes – Database Manager for Forms plugin for WordPress contains a SQL Injection vulnerability in the params parameter affecting all versions up to and including 1.4.13. The vulnerability exists due to insufficient escaping on the user-supplied parameter and a lack of sufficient preparation on the existing SQL query. This flaw allows authenticated attackers with Administrator-level access or above to append additional SQL queries into already existing queries, enabling extraction of sensitive information from the database.

Critical Impact

Authenticated attackers with administrative privileges can exploit this SQL Injection vulnerability to extract sensitive data from the WordPress database, potentially compromising user credentials, personal information, and other confidential data stored within the application.

Affected Products

• Form Vibes – Database Manager for Forms plugin for WordPress versions up to and including 1.4.13

Technical Details for CVE-2025-13409

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) affects the Form Vibes plugin's analytics module. The root issue lies in how user input through the params parameter is processed before being incorporated into SQL queries. The plugin fails to properly sanitize or escape user-supplied data, and the existing SQL query lacks parameterized prepared statements, creating an opportunity for injection attacks.

While the vulnerability requires administrative authentication to exploit, it still presents a significant risk in scenarios involving compromised admin accounts, insider threats, or multi-tenant WordPress installations where administrative access may be shared or delegated. Successful exploitation could allow an attacker to extract sensitive information from the entire WordPress database.

Root Cause

The vulnerability stems from improper input validation and lack of parameterized queries in the analytics module of the Form Vibes plugin. Specifically, the params parameter is directly incorporated into SQL queries without sufficient escaping or the use of prepared statements. The vulnerable code can be observed in the analytics module at lines 51 and 62 of module.php. WordPress provides the $wpdb->prepare() method specifically to prevent SQL injection attacks, but this security measure was not properly implemented in the affected code paths.

Attack Vector

The attack requires network access and authenticated administrative privileges. An attacker with administrator-level access can craft malicious input through the params parameter to manipulate SQL queries. By injecting carefully constructed SQL statements, the attacker can append additional queries to existing database operations, potentially extracting sensitive data such as user credentials, email addresses, form submission data, or other confidential information stored in the WordPress database.

The vulnerability manifests in the analytics module's query handling. Technical details are available in the WordPress Plugin Module Code and the Wordfence Vulnerability Report.

Detection Methods for CVE-2025-13409

Indicators of Compromise

• Unusual database queries containing SQL injection payloads such as UNION SELECT, OR 1=1, or comment sequences in the params parameter
• Unexpected database read operations originating from the Form Vibes analytics module endpoints
• Administrator accounts accessing analytics features at unusual times or frequencies
• Database error logs showing malformed SQL queries related to the Form Vibes plugin

Detection Strategies

• Monitor web application firewall (WAF) logs for SQL injection patterns targeting Form Vibes plugin endpoints
• Implement database activity monitoring to detect anomalous query patterns, particularly those involving data extraction
• Review WordPress audit logs for suspicious administrator activity related to the Form Vibes plugin
• Deploy intrusion detection rules to identify common SQL injection techniques in HTTP parameters

Monitoring Recommendations

• Enable verbose logging for the WordPress database layer to capture all queries executed by the Form Vibes plugin
• Configure alerting for database queries that return unusually large result sets from the analytics module
• Implement real-time monitoring of administrator sessions for signs of account compromise
• Regularly audit access logs for the /wp-admin/ path focusing on Form Vibes plugin interactions

How to Mitigate CVE-2025-13409

Immediate Actions Required

• Update the Form Vibes – Database Manager for Forms plugin to a version newer than 1.4.13 immediately
• Review WordPress administrator accounts and ensure only trusted users have administrative access
• Audit database access logs for any signs of exploitation prior to patching
• Consider temporarily disabling the Form Vibes plugin if an immediate update is not possible

Patch Information

A patch for this vulnerability is available in the Form Vibes plugin. The fix can be reviewed in the WordPress Plugin Changeset. Users should update to the latest version of the plugin through the WordPress admin dashboard or by manually downloading the updated version from the WordPress plugin repository.

Workarounds

• Implement a Web Application Firewall (WAF) with SQL injection detection rules to filter malicious requests targeting the Form Vibes plugin
• Restrict administrative access to only essential personnel and implement strong authentication mechanisms such as two-factor authentication
• Consider disabling or removing the Form Vibes plugin if analytics functionality is not critical to operations
• Apply database-level access controls to limit the scope of potential data extraction

# Configuration example for restricting plugin access via .htaccess
# Add to WordPress .htaccess to limit access to Form Vibes endpoints
<IfModule mod_rewrite.c>
  RewriteEngine On
  # Block suspicious SQL injection patterns in query strings
  RewriteCond %{QUERY_STRING} (union.*select|select.*from|insert.*into|drop.*table) [NC]
  RewriteRule ^(.*)$ - [F,L]
</IfModule>
