CVE-2025-14067: WordPress Easy Form Builder Auth Bypass

CVE-2025-14067 Overview

The Easy Form Builder plugin for WordPress contains an authorization bypass vulnerability affecting all versions up to and including 3.9.3. This security flaw allows authenticated attackers with Subscriber-level access or above to retrieve sensitive form response data without proper authorization. The vulnerability exists due to a missing capability check on multiple AJAX actions, enabling unauthorized access to messages, admin replies, and user information submitted through forms.

Critical Impact

Authenticated attackers with minimal privileges (Subscriber-level) can access sensitive form submission data including user messages, administrative replies, and personally identifiable information, potentially leading to data breaches and privacy violations.

Affected Products

• Easy Form Builder plugin for WordPress versions up to and including 3.9.3
• WordPress sites utilizing affected Easy Form Builder versions
• All form submissions processed through the vulnerable plugin

Technical Details for CVE-2025-14067

Vulnerability Analysis

This vulnerability falls under CWE-862 (Missing Authorization), a category of broken access control flaws. The Easy Form Builder plugin fails to implement proper capability checks on multiple AJAX action handlers, allowing low-privileged users to access administrative functions intended only for site administrators.

The core issue stems from a logic error in the authorization check implementation within the plugin's admin class. The vulnerable code uses an AND (&&) logical operator instead of an OR (||) operator when validating user permissions. This implementation error means that the authorization check fails to properly restrict access, allowing users who meet only one condition (being authenticated) to bypass the intended access controls.

When exploited, attackers can retrieve form response data that should only be accessible to administrators, including private messages between users and administrators, sensitive user information submitted through forms, and internal administrative notes.

Root Cause

The root cause is improper implementation of authorization logic in the class-Emsfb-admin.php file. The vulnerable code at line 709 contains a flawed conditional statement that uses AND (&&) instead of OR (||) when checking user capabilities. This logic error allows the check to pass under conditions where it should fail, effectively bypassing the intended authorization mechanism. The vulnerable code can be examined in the WordPress plugin repository.

Attack Vector

The attack vector is network-based, requiring no user interaction. An attacker needs only a valid Subscriber-level account on the target WordPress site. Once authenticated, the attacker can craft malicious AJAX requests to the vulnerable endpoints. Since the capability check is improperly implemented, these requests bypass authorization controls and return sensitive form data that should be restricted to administrators.

The attack can be executed by:

1. Registering or compromising a Subscriber-level account on the target WordPress site
2. Authenticating to the WordPress dashboard
3. Sending crafted AJAX requests to the vulnerable endpoints
4. Retrieving unauthorized form submission data from the server response

Detection Methods for CVE-2025-14067

Indicators of Compromise

• Unusual AJAX requests to Easy Form Builder admin endpoints from non-administrator user sessions
• Subscriber or Contributor accounts accessing form submission data or administrative functions
• Unexpected data access patterns in WordPress access logs showing form data retrieval by low-privileged users
• Multiple requests to admin-ajax.php with Easy Form Builder action parameters from suspicious user accounts

Detection Strategies

• Monitor WordPress AJAX requests for Easy Form Builder actions originating from non-administrator accounts
• Implement logging for all form data access attempts and review for unauthorized access patterns
• Configure Web Application Firewall (WAF) rules to detect and alert on suspicious AJAX activity targeting plugin endpoints
• Review WordPress user activity logs for Subscriber-level accounts accessing administrative plugin functions

Monitoring Recommendations

• Enable detailed logging for WordPress AJAX requests and regularly audit access patterns
• Monitor for newly created Subscriber accounts that immediately attempt to access plugin administrative functions
• Implement real-time alerting for data access anomalies in form submission retrievals
• Regularly review user privilege levels and remove unnecessary Subscriber accounts

How to Mitigate CVE-2025-14067

Immediate Actions Required

• Update Easy Form Builder plugin to the latest patched version immediately
• Audit recent form data access logs to identify potential unauthorized access
• Review Subscriber-level accounts for any suspicious activity or unauthorized data retrieval
• Consider temporarily disabling the Easy Form Builder plugin if immediate patching is not possible

Patch Information

The vulnerability has been addressed in the WordPress plugin repository. The fix is available in WordPress Changeset #3422020, which corrects the authorization logic error by replacing the AND (&&) operator with OR (||) in the capability check. Site administrators should update to the latest version of Easy Form Builder through the WordPress admin dashboard or by downloading the patched version directly from the WordPress plugin repository.

Workarounds

• Temporarily disable the Easy Form Builder plugin until the patch can be applied
• Restrict user registration on WordPress sites using the vulnerable plugin to prevent creation of attacker-controlled Subscriber accounts
• Implement additional WAF rules to block AJAX requests to vulnerable Easy Form Builder endpoints from non-administrator users
• Consider using a security plugin to add additional capability checks on AJAX handlers

# Configuration example - Disable Easy Form Builder plugin via WP-CLI
wp plugin deactivate easy-form-builder

# Verify current plugin version
wp plugin get easy-form-builder --field=version

# Update to patched version when available
wp plugin update easy-form-builder
