CRM Memberships <= 2.6 — Missing Authorization to Privilege Escalation via Unauthenticated Password Reset in 'ntzcrm_changepassword' AJAX Endpoint

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under CRM Memberships.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 2.7, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch CRM Memberships to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Athiwat Tiprasaharn (Jitlada).

The CRM Memberships plugin for WordPress is vulnerable to privilege escalation via password reset in all versions up to, and including, 2.6. This is due to missing authorization and authentication checks on the `ntzcrm_changepassword` AJAX action. This makes it possible for unauthenticated attackers to reset arbitrary user passwords and gain unauthorized access to user accounts via the `ntzcrm_changepassword` endpoint, granted they can obtain or enumerate a target user's email address. The plugin also exposes the `ntzcrm_get_users` endpoint without authentication, allowing attackers to enumerate subscriber email addresses, facilitating the exploitation of the password reset vulnerability.
