CVE-2025-66139: Audier For Elementor Auth Bypass Flaw

CVE-2025-66139 Overview

CVE-2025-66139 is a Missing Authorization vulnerability affecting the Audier For Elementor WordPress plugin (audier-elementor) developed by merkulove. This broken access control vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially gaining unauthorized access to restricted functionality within WordPress sites using this plugin.

Critical Impact

Attackers can bypass authorization checks to access or modify resources that should be restricted, potentially compromising site integrity and sensitive data.

Affected Products

• Audier For Elementor plugin versions up to and including 1.0.9
• WordPress sites utilizing the audier-elementor plugin
• Elementor-based websites with the Audier addon installed

Technical Details for CVE-2025-66139

Vulnerability Analysis

This vulnerability is classified under CWE-862 (Missing Authorization), which occurs when the software does not perform an authorization check when an actor attempts to access a resource or perform an action. In the context of the Audier For Elementor plugin, this means that certain functions or endpoints that should require proper user role verification are accessible without adequate authorization checks.

WordPress plugins that extend Elementor functionality often register AJAX handlers or REST API endpoints to provide dynamic features. When these handlers fail to verify user capabilities before executing privileged operations, unauthorized users can invoke these functions, leading to potential data manipulation, information disclosure, or privilege escalation.

Root Cause

The root cause is the absence of proper capability checks within the plugin's code paths that handle sensitive operations. WordPress provides functions such as current_user_can() to verify whether the current user has specific capabilities before performing actions. When developers omit these checks, any authenticated user—or in some cases, unauthenticated visitors—can trigger functionality intended only for administrators or editors.

Attack Vector

The attack vector involves sending crafted requests directly to vulnerable plugin endpoints or AJAX handlers. An attacker would identify exposed functions that lack authorization validation and then invoke them to perform unauthorized operations. This could include accessing restricted content, modifying plugin settings, or manipulating data managed by the Audier For Elementor plugin.

Detection Methods for CVE-2025-66139

Indicators of Compromise

• Unexpected changes to Audier For Elementor plugin settings or configurations
• Unusual AJAX requests targeting audier-elementor endpoints in web server logs
• Unauthorized content modifications on pages utilizing Audier widgets
• Access log entries showing repeated requests to plugin-specific endpoints from unexpected user roles

Detection Strategies

• Monitor WordPress AJAX handler requests for suspicious activity targeting the audier-elementor plugin
• Implement Web Application Firewall (WAF) rules to detect and block unauthorized access attempts to plugin endpoints
• Review WordPress user activity logs for actions performed by users without appropriate permissions
• Deploy endpoint monitoring to detect anomalous request patterns to WordPress admin-ajax.php

Monitoring Recommendations

• Enable comprehensive logging for all WordPress AJAX and REST API requests
• Configure alerting for failed authorization attempts and unexpected plugin-related requests
• Regularly audit user roles and capabilities within WordPress installations
• Implement file integrity monitoring for plugin directories to detect unauthorized modifications

How to Mitigate CVE-2025-66139

Immediate Actions Required

• Update the Audier For Elementor plugin to a patched version when available from the developer
• If no patch is available, consider temporarily deactivating the plugin until a fix is released
• Review and restrict user roles to minimize the attack surface
• Implement additional access controls at the web server or WAF level to protect vulnerable endpoints

Patch Information

At the time of publication, users should check the WordPress plugin repository or the developer's official channels for updates to the Audier For Elementor plugin that address this vulnerability. The vulnerability affects versions from the initial release through 1.0.9. Monitor the Patchstack advisory for updated patch information.

Workarounds

• Temporarily disable the Audier For Elementor plugin if it is not critical to site functionality
• Implement capability checks at the theme or custom plugin level to protect sensitive operations
• Use a security plugin to add additional authorization layers for AJAX handlers
• Restrict access to WordPress admin-ajax.php from untrusted IP ranges if feasible

# Example: Restrict AJAX access in Apache .htaccess (adjust as needed for your environment)
<Files admin-ajax.php>
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
    Allow from YOUR_TRUSTED_IP
</Files>
