CVE-2025-66135: Imager for Elementor Auth Bypass Flaw

CVE-2025-66135 Overview

CVE-2025-66135 is a Missing Authorization vulnerability affecting the Imager for Elementor WordPress plugin developed by merkulove. This broken access control vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized actions within WordPress installations running the vulnerable plugin.

The vulnerability stems from CWE-862 (Missing Authorization), indicating that the plugin fails to properly verify user permissions before allowing access to sensitive functionality. This type of flaw can enable unauthenticated or low-privileged users to perform actions that should be restricted to administrators or other authorized roles.

Critical Impact

Attackers can bypass access control mechanisms to perform unauthorized actions within WordPress sites using Imager for Elementor plugin versions through 2.0.4.

Affected Products

• Imager for Elementor WordPress plugin versions from n/a through 2.0.4
• WordPress installations with the imager-elementor plugin installed
• Sites using Elementor page builder with the Imager addon

Technical Details for CVE-2025-66135

Vulnerability Analysis

This vulnerability represents a fundamental access control failure in the Imager for Elementor plugin. The plugin fails to implement proper authorization checks before processing certain requests, allowing users without appropriate privileges to access protected functionality.

Missing authorization vulnerabilities in WordPress plugins are particularly dangerous because they can be exploited remotely without authentication. In the context of a page builder addon like Imager for Elementor, this could potentially allow attackers to manipulate image processing features, access media files, or perform other plugin-specific actions reserved for administrators.

The vulnerability was classified under CWE-862, which specifically addresses scenarios where software does not perform authorization checks when an actor attempts to access a resource or perform an action. This represents a design flaw rather than an implementation bug, suggesting the authorization logic was never properly implemented for affected functionality.

Root Cause

The root cause of CVE-2025-66135 is the absence of capability checks in plugin functions that should be restricted to authorized users. WordPress provides built-in functions such as current_user_can() to verify user capabilities before executing sensitive operations. The Imager for Elementor plugin fails to utilize these mechanisms properly, leaving certain endpoints or actions accessible to unauthorized users.

This type of vulnerability often occurs when developers assume that obscure function names or AJAX endpoints provide sufficient security through obscurity, rather than implementing proper permission validation.

Attack Vector

The attack vector for this vulnerability involves exploiting the broken access control to perform unauthorized actions. An attacker could potentially:

1. Identify unprotected AJAX endpoints or plugin functions
2. Craft malicious requests to these endpoints without proper authentication
3. Execute restricted functionality without having the required WordPress capabilities
4. Potentially modify plugin settings, access protected content, or perform other privileged operations

Since this is a WordPress plugin vulnerability, exploitation typically occurs over the network through HTTP requests to the WordPress AJAX handler or REST API endpoints exposed by the plugin.

The vulnerability can be exploited by sending crafted requests to plugin endpoints that lack proper authorization validation. Technical details and proof-of-concept information may be available through the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-66135

Indicators of Compromise

• Unexpected modifications to WordPress media library or image settings
• Unusual HTTP requests to admin-ajax.php with Imager for Elementor action parameters from unauthenticated users
• Log entries showing access to restricted plugin functionality from non-administrative user roles
• Changes to plugin configuration without corresponding administrative activity

Detection Strategies

• Monitor WordPress access logs for requests to plugin-specific AJAX actions from unauthenticated sessions
• Implement Web Application Firewall (WAF) rules to detect and block exploitation attempts targeting the plugin
• Deploy SentinelOne Singularity for endpoint monitoring to detect post-exploitation activity
• Audit WordPress plugin activity logs for unauthorized configuration changes

Monitoring Recommendations

• Enable detailed logging for WordPress AJAX requests and REST API calls
• Configure alerts for failed authorization attempts in WordPress security plugins
• Monitor for enumeration of plugin endpoints which often precedes exploitation
• Implement network-level monitoring for suspicious request patterns to WordPress installations

How to Mitigate CVE-2025-66135

Immediate Actions Required

• Update Imager for Elementor plugin to a patched version when available (versions above 2.0.4)
• If no patch is available, consider temporarily deactivating the imager-elementor plugin until a fix is released
• Implement additional access controls at the web server or WAF level to restrict plugin endpoint access
• Review WordPress user accounts and remove unnecessary administrative privileges

Patch Information

Organizations running affected versions of Imager for Elementor should monitor the plugin's official update channels and the Patchstack vulnerability database for patch availability. Update to a version higher than 2.0.4 once a security patch is released by the vendor merkulove.

Workarounds

• Temporarily disable the Imager for Elementor plugin if not critical to site functionality
• Implement IP-based access restrictions to limit who can reach WordPress admin functionality
• Use a WordPress security plugin with virtual patching capabilities to block exploitation attempts
• Configure web server rules to restrict direct access to admin-ajax.php from unauthenticated users where possible

# Example .htaccess rule to restrict AJAX access (Apache)
# Place in WordPress root directory
<Files admin-ajax.php>
    <RequireAll>
        Require all granted
        # Add additional restrictions as needed for your environment
    </RequireAll>
</Files>
