Technical Details for CVE-2025-68046

Vulnerability Analysis

This vulnerability exists within the ThemeHunk Contact Form & Lead Form Elementor Builder plugin, a WordPress plugin designed to create contact forms and lead generation forms using the Elementor page builder. The issue stems from improper handling of sensitive system information, which becomes accessible to unauthorized parties.

The vulnerability allows attackers to retrieve embedded sensitive data without proper authentication or authorization checks. This type of information exposure can reveal internal system configurations, file paths, database structures, or other technical details that should remain protected from external access.

WordPress plugins handling form data often process and store sensitive information. When these plugins fail to properly restrict access to system-level data, attackers can enumerate valuable information about the target environment to plan more sophisticated attacks.

Root Cause

The root cause of this vulnerability is the plugin's failure to properly restrict access to sensitive system information. The plugin exposes internal data that should be protected from unauthorized access, violating the principle of least privilege and information hiding.

This occurs due to insufficient access controls on endpoints or functions that handle or display system-level information, allowing unauthenticated or low-privileged users to access data intended only for administrators.

Attack Vector

An attacker can exploit this vulnerability by interacting with the vulnerable plugin endpoints to extract sensitive system information. The attack requires network access to the WordPress installation but does not require authentication, making it exploitable by any remote attacker who can reach the target website.

The exposed information could include server configurations, file system paths, database connection details, or other sensitive data that aids in reconnaissance for subsequent attacks.

Detection Methods for CVE-2025-68046

Indicators of Compromise

• Unusual access patterns to WordPress plugin endpoints associated with lead-form-builder
• Unexpected requests to form builder configuration or system information endpoints
• Log entries showing unauthorized access attempts to plugin resources
• Anomalous data exfiltration patterns from WordPress installations

Detection Strategies

• Monitor web server access logs for suspicious requests targeting /wp-content/plugins/lead-form-builder/ paths
• Implement Web Application Firewall (WAF) rules to detect information disclosure attempts
• Review WordPress activity logs for unauthorized access to plugin settings or data
• Deploy file integrity monitoring to detect unauthorized changes to plugin files

Monitoring Recommendations

• Enable verbose logging for WordPress and the affected plugin
• Configure alerts for access attempts to sensitive plugin endpoints from external IP addresses
• Implement rate limiting on form builder endpoints to detect enumeration attempts
• Monitor outbound traffic for potential data exfiltration containing system information

How to Mitigate CVE-2025-68046

Immediate Actions Required

• Update ThemeHunk Contact Form & Lead Form Elementor Builder to a version newer than 2.0.1 when a patch becomes available
• Review plugin permissions and restrict access to administrative functions
• Implement Web Application Firewall rules to block suspicious requests to the plugin
• Audit WordPress installations for signs of exploitation or data exposure

Patch Information

Organizations should monitor the Patchstack Vulnerability Report for updates on patched versions. Update to the latest version of the plugin as soon as a security fix is released by ThemeHunk.

Workarounds

• Temporarily disable the Contact Form & Lead Form Elementor Builder plugin if it is not critical to operations
• Implement additional access controls at the web server level to restrict access to plugin endpoints
• Use a WordPress security plugin to add additional authentication layers to sensitive plugin functions
• Consider using an alternative form builder plugin until a patch is available

# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate lead-form-builder

# Alternatively, restrict access via .htaccess
# Add to WordPress root .htaccess file
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^wp-content/plugins/lead-form-builder/.*$ - [F,L]
</IfModule>
