CVE-2026-22472: Easy Form Builder Auth Bypass Vulnerability

CVE-2026-22472 Overview

CVE-2026-22472 is a Missing Authorization vulnerability in the Easy Form Builder WordPress plugin developed by hassantafreshi. This security flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to plugin functionality. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the plugin fails to properly verify that users have the required permissions before allowing access to protected resources or actions.

Critical Impact

Unauthorized users may be able to access or modify form data and plugin settings without proper authentication, potentially compromising sensitive information collected through forms on affected WordPress sites.

Affected Products

• Easy Form Builder WordPress Plugin versions up to and including 3.9.6
• WordPress installations running vulnerable Easy Form Builder versions
• Websites using Easy Form Builder for data collection and form management

Technical Details for CVE-2026-22472

Vulnerability Analysis

This vulnerability stems from a Broken Access Control weakness in the Easy Form Builder plugin's authorization mechanisms. The plugin fails to implement proper capability checks before allowing users to perform sensitive operations. In WordPress plugin development, access control is typically enforced through capability checks using functions like current_user_can(). When these checks are missing or improperly implemented, unauthorized users—including unauthenticated visitors or users with minimal privileges—can access administrative functions or sensitive data.

The Missing Authorization vulnerability (CWE-862) means the plugin does not verify that a user performing an action has the appropriate WordPress role or capability to do so. This is particularly dangerous in form builder plugins as they often handle sensitive user-submitted data including personal information, contact details, and other confidential submissions.

Root Cause

The root cause of this vulnerability is the absence of proper authorization checks within the Easy Form Builder plugin's code. Specifically, the plugin exposes certain AJAX endpoints or administrative functions without verifying that the requesting user has the necessary WordPress capabilities. This design flaw allows users with insufficient privileges to invoke protected functionality by directly accessing the vulnerable endpoints.

Attack Vector

An attacker can exploit this vulnerability by sending crafted requests to the vulnerable plugin endpoints without proper authorization. The attack can be executed by any authenticated user regardless of their assigned role, or potentially by unauthenticated visitors depending on the specific vulnerable function. Attackers may be able to:

• Access form submission data without administrative privileges
• Modify form configurations or settings
• Export or delete collected form data
• Bypass intended access restrictions within the plugin

For detailed technical information about the exploitation mechanism, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2026-22472

Indicators of Compromise

• Unexpected access to form submission data by non-administrative users
• Unusual AJAX requests to Easy Form Builder plugin endpoints from low-privilege or unauthenticated sessions
• Modifications to form settings or configurations without corresponding administrative user activity
• Anomalous export or deletion of form data in plugin logs

Detection Strategies

• Monitor WordPress AJAX requests targeting easy-form-builder plugin endpoints for unauthorized access attempts
• Implement web application firewall (WAF) rules to detect and block suspicious requests to plugin administrative functions
• Review WordPress access logs for patterns indicating privilege escalation or unauthorized data access
• Audit user role assignments and verify that sensitive plugin operations require appropriate capabilities

Monitoring Recommendations

• Enable detailed logging for the Easy Form Builder plugin to track user actions and access patterns
• Configure WordPress security plugins to alert on unauthorized access attempts to administrative functions
• Implement real-time monitoring for changes to form configurations and bulk data operations
• Review server access logs periodically for suspicious POST requests to WordPress AJAX handlers

How to Mitigate CVE-2026-22472

Immediate Actions Required

• Update the Easy Form Builder plugin to a patched version newer than 3.9.6 when available
• Temporarily deactivate the Easy Form Builder plugin if an immediate update is not available and the risk is unacceptable
• Review access logs for any signs of exploitation and investigate suspicious activity
• Restrict access to the WordPress admin area through IP allowlisting or additional authentication where possible

Patch Information

Users should monitor the official WordPress plugin repository and the Patchstack Vulnerability Report for updates regarding a security patch. Once a patched version is released, update immediately through the WordPress admin dashboard or via WP-CLI.

Workarounds

• Implement a Web Application Firewall (WAF) with rules to restrict access to Easy Form Builder AJAX endpoints to authenticated administrators only
• Use a WordPress security plugin to add additional capability checks on sensitive plugin functions
• Restrict user registration and minimize the number of users with access to the WordPress dashboard
• Consider temporarily using an alternative form builder plugin until a patch is available

# WP-CLI command to check current Easy Form Builder version
wp plugin list --name=easy-form-builder --fields=name,version,status

# Update the plugin when a patched version becomes available
wp plugin update easy-form-builder

# Alternatively, deactivate the plugin temporarily if no patch is available
wp plugin deactivate easy-form-builder
