CVE-2025-58672: WP User Frontend Auth Bypass Vulnerability

CVE-2025-58672 Overview

CVE-2025-58672 is a missing authorization vulnerability [CWE-862] in the weDevs WP User Frontend plugin for WordPress. The flaw affects all versions up to and including 4.1.12. Attackers with low-privilege authenticated access can exploit incorrectly configured access control security levels to perform actions outside their intended permission scope. The vulnerability is network-exploitable and requires no user interaction, though it does require authentication. Successful exploitation can compromise data integrity and availability within affected WordPress installations.

Critical Impact

Authenticated users with minimal privileges can bypass access controls in the WP User Frontend plugin, leading to unauthorized modifications to plugin-managed data and functionality.

Affected Products

• weDevs WP User Frontend plugin for WordPress
• All versions from initial release through 4.1.12
• WordPress sites deploying the plugin for front-end user content management

Technical Details for CVE-2025-58672

Vulnerability Analysis

The vulnerability stems from missing authorization checks within the WP User Frontend plugin. The plugin exposes functionality that should be restricted to specific user roles but fails to validate whether the requesting user holds the required capability. This gap enables users with low privileges to trigger sensitive plugin operations reserved for higher-privileged accounts.

The issue falls under CWE-862: Missing Authorization. Broken access control patterns typically appear when plugin developers rely on client-side restrictions or authentication alone rather than server-side capability checks such as WordPress current_user_can() calls. Exploitation of the flaw affects both integrity and availability of plugin-managed content and settings.

Root Cause

The root cause is incorrectly configured access control security levels within the plugin's request handlers. Endpoints that perform privileged operations do not enforce role or capability verification before executing the requested action. Any authenticated session, regardless of role, can reach these handlers and complete actions intended for administrators or elevated roles.

Attack Vector

An attacker requires an authenticated account on the target WordPress site, such as a subscriber or contributor account created through open registration. The attacker sends crafted HTTP requests to affected plugin endpoints exposed by WP User Frontend versions through 4.1.12. Because the plugin does not verify authorization, the request executes with the plugin's intended privilege level rather than the user's actual role.

For technical exploitation details, see the Patchstack WP User Frontend Vulnerability advisory.

Detection Methods for CVE-2025-58672

Indicators of Compromise

• Unexpected changes to WP User Frontend forms, submissions, or plugin configuration performed by low-privileged accounts
• HTTP POST requests to plugin AJAX or REST endpoints originating from subscriber-level sessions
• Newly created or modified posts, user profiles, or uploaded files attributed to accounts that lack the corresponding WordPress capability

Detection Strategies

• Review WordPress audit logs for privilege inconsistencies between the acting user's role and the action performed through the WP User Frontend plugin
• Correlate web server access logs with authenticated session identifiers to identify low-privileged users invoking administrative plugin endpoints
• Deploy WordPress-specific security monitoring plugins that flag actions performed without a matching capability check

Monitoring Recommendations

• Track the installed version of WP User Frontend across all managed WordPress sites and alert on any instance at or below 4.1.12
• Monitor for spikes in authenticated requests to admin-ajax.php and REST routes that map to WP User Frontend handlers
• Alert on new user account creation followed by immediate access to plugin management functionality

How to Mitigate CVE-2025-58672

Immediate Actions Required

• Update the weDevs WP User Frontend plugin to a version released after 4.1.12 that addresses the missing authorization defect
• Audit existing WordPress user accounts and disable or delete accounts that are not required, particularly self-registered low-privilege accounts
• Review recent plugin activity for unauthorized changes and roll back suspicious modifications from clean backups

Patch Information

Refer to the Patchstack advisory for WP User Frontend for the fixed release and vendor guidance. Apply the updated plugin package through the WordPress admin dashboard or by replacing the plugin files directly on the server.

Workarounds

• Temporarily deactivate the WP User Frontend plugin if an immediate patch cannot be applied
• Restrict new user registration on affected sites to prevent unauthenticated attackers from obtaining the low-privilege account required for exploitation
• Place the WordPress admin and plugin AJAX endpoints behind a web application firewall rule that enforces role-based access to WP User Frontend actions

# Example: disable open user registration in wp-config.php until patched
define( 'DISALLOW_FILE_MODS', false );
# In WordPress admin, navigate to Settings > General and uncheck
# "Anyone can register" to reduce the attacker's ability to obtain
# the authenticated session required for exploitation.
