CVE-2025-69052: WooCommerce Mobile Auth Bypass Flaw

CVE-2025-69052 Overview

A Missing Authorization vulnerability has been identified in the FmeAddons "Registration & Login with Mobile Phone Number for WooCommerce" WordPress plugin. This vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to protected functionality within the plugin.

The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the plugin fails to properly verify that a user has been authorized to access specific resources or functionality before granting access.

Critical Impact

Attackers may exploit broken access control to bypass authentication mechanisms, access restricted user data, or perform unauthorized actions within WooCommerce environments using mobile phone number registration.

Affected Products

• FmeAddons Registration & Login with Mobile Phone Number for WooCommerce versions up to and including 1.3.1
• WordPress installations using the registration-login-with-mobile-phone-number plugin
• WooCommerce stores relying on mobile phone number authentication

Technical Details for CVE-2025-69052

Vulnerability Analysis

This vulnerability stems from insufficient authorization checks within the plugin's core functionality. The Missing Authorization flaw (CWE-862) allows attackers to access protected resources or execute privileged operations without proper verification of their access rights.

In the context of this WooCommerce plugin, which handles user registration and login via mobile phone numbers, the broken access control could allow unauthorized users to manipulate registration processes, access other users' account information, or bypass authentication workflows entirely.

Root Cause

The root cause is the absence of proper authorization verification before executing sensitive operations. The plugin does not adequately validate whether the requesting user has the necessary permissions to perform certain actions. This is a common vulnerability pattern in WordPress plugins where developers implement authentication but neglect to implement proper authorization checks for specific endpoints or functions.

According to the Patchstack WordPress Vulnerability Report, this vulnerability allows exploitation of incorrectly configured access control security levels.

Attack Vector

The attack vector involves sending crafted requests to vulnerable plugin endpoints that lack proper authorization checks. An attacker could potentially:

1. Access AJAX handlers or REST API endpoints without proper capability checks
2. Manipulate user registration or login processes for other accounts
3. Access or modify mobile phone number associations for users
4. Bypass intended workflow restrictions within the plugin

Since no verified code examples are available for this vulnerability, administrators should review the plugin's AJAX handlers and ensure all sensitive operations include proper current_user_can() capability checks before processing requests.

Detection Methods for CVE-2025-69052

Indicators of Compromise

• Unexpected user account modifications or registrations in WooCommerce
• Anomalous API or AJAX requests targeting the registration-login-with-mobile-phone-number plugin endpoints
• Unauthorized changes to mobile phone number associations in user accounts
• Suspicious activity in WordPress access logs related to plugin-specific endpoints

Detection Strategies

• Monitor WordPress access logs for unusual patterns of requests to plugin endpoints
• Implement Web Application Firewall (WAF) rules to detect and block unauthorized access attempts
• Review WooCommerce user activity logs for unexpected account changes
• Deploy intrusion detection systems configured to alert on broken access control patterns

Monitoring Recommendations

• Enable detailed logging for WordPress AJAX and REST API requests
• Set up alerts for failed authentication attempts and unusual user registration patterns
• Monitor for mass enumeration attempts against user endpoints
• Regularly audit user accounts for unauthorized modifications

How to Mitigate CVE-2025-69052

Immediate Actions Required

• Update the "Registration & Login with Mobile Phone Number for WooCommerce" plugin to the latest patched version if available
• Temporarily disable the plugin if no patch is available and it is not critical to operations
• Implement additional access control measures at the web server or WAF level
• Review and audit existing user accounts for signs of compromise

Patch Information

Site administrators should check for updates to the FmeAddons "Registration & Login with Mobile Phone Number for WooCommerce" plugin through the WordPress plugin repository. Refer to the Patchstack vulnerability database for the latest information on patched versions and remediation guidance.

Workarounds

• Restrict access to WordPress admin and AJAX endpoints using IP-based access controls
• Implement a Web Application Firewall (WAF) with rules specific to WordPress and WooCommerce
• Consider using a security plugin to add additional capability checks and access logging
• Limit user registration capabilities if mobile phone authentication is not critical

# Example: Restrict access to WordPress AJAX handlers via .htaccess
# Add to your WordPress root .htaccess file

<Files admin-ajax.php>
    <RequireAll>
        Require all granted
        # Add additional restrictions as needed
    </RequireAll>
</Files>

# Enable access logging for security monitoring
# Ensure mod_log_config is enabled in Apache
