CVE-2025-32210: CM Registration Authorization Bypass Flaw

CVE-2025-32210 Overview

CVE-2025-32210 is a Missing Authorization vulnerability [CWE-862] in the CreativeMindsSolutions CM Registration and Invitation Codes plugin for WordPress (cm-invitation-codes). The flaw affects all versions up to and including 2.5.6. Authenticated attackers with low privileges can exploit incorrectly configured access control checks to perform actions restricted to higher-privileged roles. The vulnerability integrity impact is high, while confidentiality and availability are unaffected. Exploitation requires network access and no user interaction.

Critical Impact
A low-privileged authenticated user can bypass access control checks in the plugin and modify data or invitation code state that should be restricted to administrators.

Affected Products

CreativeMindsSolutions CM Registration and Invitation Codes (cm-invitation-codes) plugin for WordPress
All versions from n/a through 2.5.6
WordPress sites that expose the plugin's action handlers to authenticated subscribers

Technical Details for CVE-2025-32210

Vulnerability Analysis

The plugin exposes one or more action handlers that fail to verify the caller's role or capability before executing privileged operations. According to the Patchstack Vulnerability Report, the issue is classified as broken access control. Because the missing check permits any authenticated user to invoke the handler, a subscriber-level account is sufficient to reach code paths intended for administrators. The integrity impact is high because affected endpoints allow state changes to plugin data.

Root Cause

The root cause is a missing authorization check on plugin action endpoints. The plugin relies on nonces or authentication alone without validating the user's WordPress capabilities using current_user_can() or an equivalent role check. This maps directly to CWE-862 (Missing Authorization). Any code path that mutates invitation codes, registration settings, or related data becomes reachable by lower-privileged accounts.

Attack Vector

An attacker first registers or obtains any authenticated WordPress account on the target site. The attacker then issues a crafted HTTP request to the vulnerable plugin action, supplying valid session credentials and any required nonce. Because the handler does not verify the caller's role, the server executes the privileged operation and returns a success response. See the referenced Patchstack advisory for endpoint-level detail.

Detection Methods for CVE-2025-32210

Indicators of Compromise

Unexpected creation, modification, or deletion of invitation codes managed by the cm-invitation-codes plugin
Requests to plugin action endpoints (admin-ajax.php or admin-post.php with plugin-specific action parameters) originating from subscriber-level user sessions
New administrator or elevated-role accounts registered shortly after invitation code changes
Unexplained modifications to plugin option rows in the wp_options table

Detection Strategies

Review WordPress access logs for POST requests to admin-ajax.php where the action parameter references the CM Registration and Invitation Codes plugin and the authenticated user is not an administrator.
Correlate WordPress audit logs with role and capability changes to identify privilege discrepancies between the requester and the action performed.
Compare current plugin data and options against known-good backups to identify unauthorized state changes.

Monitoring Recommendations

Enable a WordPress activity logging plugin to capture user, IP, and action metadata for every plugin AJAX call.
Forward web server and PHP-FPM logs to a centralized log platform and alert on subscriber accounts invoking plugin admin actions.
Monitor for anomalous authenticated session activity from new or dormant user accounts targeting /wp-admin/admin-ajax.php.

How to Mitigate CVE-2025-32210

Immediate Actions Required

Update the CM Registration and Invitation Codes plugin to a version later than 2.5.6 once released by CreativeMindsSolutions.
Audit all WordPress user accounts and remove untrusted or unused subscriber-level accounts.
Review invitation code records and plugin settings for unauthorized changes since the plugin was installed.
Restrict new user registration on sites that do not require public sign-up.

Patch Information

At the time of the last NVD update on 2026-06-17, the advisory lists affected versions through 2.5.6. Administrators should consult the Patchstack Vulnerability Report and the vendor's plugin page for the current fixed version before upgrading.

Workarounds

Disable and remove the cm-invitation-codes plugin until a patched version is installed if invitation-code functionality is not business-critical.
Deploy a Web Application Firewall (WAF) rule to block requests to the plugin's action endpoints from non-administrator sessions.
Enforce least-privilege by ensuring the default new-user role is subscriber and by restricting admin-ajax.php plugin actions through server-side ACLs where feasible.
Require multi-factor authentication for all WordPress accounts to reduce the risk of credential-based access to the vulnerable endpoint.

bash

# Configuration example: temporarily deactivate the vulnerable plugin via WP-CLI
wp plugin deactivate cm-invitation-codes
wp plugin status cm-invitation-codes
