CVE-2025-12981: Listee WordPress Privilege Escalation Flaw

CVE-2025-12981 Overview

A critical privilege escalation vulnerability has been identified in the Listee theme for WordPress, affecting all versions up to and including 1.1.6. This vulnerability exists within the bundled listee-core plugin's user registration function, where a broken validation check fails to properly sanitize the user_role parameter. This flaw enables unauthenticated attackers to register as Administrator-level users by manipulating the user_role parameter during the registration process, effectively granting complete control over the WordPress installation.

Critical Impact

Unauthenticated attackers can gain full administrative access to WordPress sites by exploiting the broken role validation in the user registration function, potentially leading to complete site takeover, data theft, and malware injection.

Affected Products

• Listee WordPress Theme versions ≤ 1.1.6
• Listee-core bundled plugin (all versions prior to patch)
• WordPress installations using the affected Listee theme

Technical Details for CVE-2025-12981

Vulnerability Analysis

This privilege escalation vulnerability (CWE-269: Improper Privilege Management) stems from inadequate input validation in the user registration workflow of the Listee WordPress theme. The vulnerability resides specifically in the listee-core-users.php file within the bundled listee-core plugin. When users register through the theme's registration form, the application processes a user_role parameter that should be restricted to standard subscriber-level roles. However, due to a broken validation check, the parameter is not properly sanitized, allowing attackers to inject arbitrary role values including "administrator".

The exploitation requires no authentication whatsoever, making this vulnerability particularly dangerous for public-facing WordPress installations. An attacker can craft a registration request with a manipulated user_role parameter set to "administrator", bypassing the intended role restrictions entirely. Upon successful exploitation, the attacker obtains full administrative privileges on the WordPress site.

Root Cause

The root cause of this vulnerability is improper input validation within the user registration function located in the listee-core/includes/listee-core-users.php file (around line 928 in version 1.1.5). The validation logic intended to restrict user role assignments during registration contains a flaw that fails to properly verify and sanitize the user_role parameter before it is applied to the newly created user account. This allows untrusted input from the registration request to directly influence the user's assigned role in the WordPress system.

Attack Vector

The attack vector is network-based and requires no prior authentication or user interaction. An attacker targeting a vulnerable WordPress site would:

1. Access the user registration endpoint provided by the Listee theme
2. Submit a registration request with standard user details (username, email, password)
3. Include a manipulated user_role parameter set to "administrator" in the request
4. The broken validation fails to reject the elevated role assignment
5. A new administrator account is created under the attacker's control
6. The attacker logs in with full administrative privileges to the WordPress site

The vulnerability can be exploited remotely against any publicly accessible WordPress installation using the affected Listee theme versions. For technical details, see the WordPress Theme Code Review.

Detection Methods for CVE-2025-12981

Indicators of Compromise

• Unexpected administrator accounts appearing in WordPress user listings
• User registration logs showing accounts created with administrator role via theme registration
• Unusual POST requests to the Listee theme registration endpoint containing user_role=administrator or similar parameters
• Recently created admin accounts with unfamiliar email addresses or usernames
• Suspicious activity from newly registered users performing administrative actions

Detection Strategies

• Monitor WordPress user creation events for accounts registered with elevated privileges
• Implement Web Application Firewall (WAF) rules to detect and block registration requests containing unauthorized role parameters
• Review Apache/Nginx access logs for POST requests to registration endpoints with suspicious payloads
• Deploy file integrity monitoring to detect unauthorized changes made by rogue administrators
• Enable WordPress audit logging to track user role assignments and administrative actions

Monitoring Recommendations

• Configure real-time alerts for any new administrator account creation
• Implement rate limiting on registration endpoints to slow automated exploitation attempts
• Set up periodic automated scans to identify unexpected users with elevated privileges
• Monitor outbound network connections from the WordPress server for signs of post-exploitation activity

How to Mitigate CVE-2025-12981

Immediate Actions Required

• Update the Listee theme to the latest patched version immediately
• Audit all existing WordPress user accounts and remove any unauthorized administrator accounts
• Review recent user registration activity for signs of exploitation
• Temporarily disable user registration if patching cannot be performed immediately
• Change credentials for all legitimate administrator accounts as a precautionary measure

Patch Information

Dreams Technologies has addressed this vulnerability in an updated version of the Listee theme. Users should update to the latest version available on ThemeForest. Refer to the Dreams Technologies Changelog for version-specific patch information. Additional technical details are available in the Wordfence Vulnerability Report.

Workarounds

• Disable user registration functionality in WordPress Settings → General until the theme can be patched
• Implement server-side filtering to reject registration requests containing user_role parameters
• Use a security plugin like Wordfence to block malicious registration attempts
• Restrict access to the registration endpoint via .htaccess rules or firewall configuration
• Consider temporarily switching to a different theme if immediate patching is not feasible

# Disable registration via wp-config.php as temporary mitigation
# Add this line to your wp-config.php file
define('DISALLOW_FILE_MODS', true);

# Or disable registration in .htaccess by blocking the registration endpoint
# Add these lines to your .htaccess file in the WordPress root
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} wp-login\.php
    RewriteCond %{QUERY_STRING} action=register
    RewriteRule ^(.*)$ - [F,L]
</IfModule>
