CVE-2025-29004: WordPress AA-Team Privilege Escalation

CVE-2025-29004 Overview

CVE-2025-29004 is a privilege escalation vulnerability affecting two WordPress plugins developed by AA-Team: Premium Age Verification / Restriction for WordPress and Responsive Coming Soon Landing Page / Holding Page for WordPress. The vulnerability stems from incorrect privilege assignment (CWE-266), which allows authenticated users with low privileges to escalate their access to higher privilege levels within the WordPress environment.

Critical Impact

Authenticated attackers can exploit this vulnerability to escalate privileges, potentially gaining administrative access to affected WordPress installations and compromising site integrity.

Affected Products

• AA-Team Premium Age Verification / Restriction for WordPress versions through 3.0.2
• AA-Team Responsive Coming Soon Landing Page / Holding Page for WordPress versions through 3.0

Technical Details for CVE-2025-29004

Vulnerability Analysis

This vulnerability is classified as an Incorrect Privilege Assignment issue (CWE-266). The affected plugins fail to properly validate or restrict privilege assignments within their functionality, enabling authenticated users to elevate their access level beyond their intended permissions. In a WordPress context, this typically means a user with a low-privilege role such as Subscriber or Contributor could potentially gain Administrator-level capabilities.

The vulnerability requires network access and low-privilege authentication to exploit, but once these conditions are met, an attacker can achieve significant impact across confidentiality, integrity, and availability of the affected WordPress installation. Successful exploitation could allow attackers to modify site content, install malicious plugins, access sensitive data, or create additional administrative accounts for persistent access.

Root Cause

The root cause lies in the improper implementation of privilege checks within the affected AA-Team plugins. The plugins do not adequately verify whether the requesting user has appropriate permissions before allowing privilege-related operations to proceed. This represents a fundamental flaw in the authorization logic, where user role validation is either missing, incomplete, or improperly implemented.

Attack Vector

The attack vector for CVE-2025-29004 is network-based, requiring an authenticated user to initiate the exploit. An attacker would need valid credentials to a WordPress account on the target site, even if only a low-privilege account. Once authenticated, the attacker can leverage the vulnerability within either affected plugin to manipulate privilege assignments.

The attack does not require user interaction beyond the attacker's own actions, making it straightforward to exploit once initial authentication is achieved. Given WordPress's widespread use and the common practice of allowing user registration on many sites, obtaining low-privilege access is often trivial for attackers.

Detection Methods for CVE-2025-29004

Indicators of Compromise

• Unexpected changes to WordPress user roles or capabilities, particularly promotions from low-privilege roles to Administrator
• Unusual administrative actions performed by accounts that should have limited access
• New administrator accounts appearing without legitimate creation events
• Plugin or theme installations initiated by non-administrative users

Detection Strategies

• Implement WordPress audit logging to track all user role changes and privilege modifications
• Monitor for anomalous administrative activity patterns from accounts with historically low-privilege roles
• Review WordPress user database for unauthorized role escalations regularly
• Deploy web application firewall (WAF) rules to detect exploitation attempts against known vulnerable plugin endpoints

Monitoring Recommendations

• Enable comprehensive logging for user authentication and authorization events in WordPress
• Set up alerts for any changes to user capabilities or role assignments outside of expected administrative workflows
• Regularly audit installed plugin versions against known vulnerability databases
• Monitor for suspicious POST requests to plugin-specific endpoints that handle user data or permissions

How to Mitigate CVE-2025-29004

Immediate Actions Required

• Immediately deactivate and remove AA-Team Premium Age Verification / Restriction for WordPress if version 3.0.2 or earlier
• Immediately deactivate and remove AA-Team Responsive Coming Soon Landing Page / Holding Page for WordPress if version 3.0 or earlier
• Audit all WordPress user accounts for unauthorized privilege escalations and remediate any discovered compromises
• Consider implementing additional access controls until patched versions are available and verified

Patch Information

Refer to the official Patchstack advisory for Premium Age Verification and Patchstack advisory for Responsive Coming Soon for the latest patching guidance. Check with the plugin vendor AA-Team for updated versions that address this vulnerability.

Workarounds

• Disable user registration on WordPress sites where the affected plugins are installed until patches are applied
• Implement strict IP-based access controls for the WordPress admin area
• Use a Web Application Firewall (WAF) with WordPress-specific rulesets to block potential exploitation attempts
• Remove the affected plugins entirely if they are not critical to site functionality
• Restrict low-privilege user access to authenticated areas of the site where possible

# WordPress configuration to disable user registration
# Add to wp-config.php or use Settings > General in admin panel
define('USERS_CAN_REGISTER', false);

# Alternatively, deactivate the vulnerable plugins via WP-CLI
wp plugin deactivate age-restriction
wp plugin deactivate wordpress-flat-countdown

# List all administrators to audit for unauthorized accounts
wp user list --role=administrator --fields=ID,user_login,user_email,user_registered
