CVE-2025-13313
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe CRM Memberships WordPress plugin (versions up to 2.6) has two critical authentication bypass vulnerabilities: the `ntzcrm_changepassword` AJAX action lacks authorization and authentication checks, allowing unauthenticated attackers to reset any user's password by knowing their email; and the `ntzcrm_get_users` endpoint exposes subscriber email addresses without authentication, enabling enumeration of targets for the password reset attack.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if CRM Memberships plugin is installedCheck the WordPress plugins directory (wp-content/plugins) for a folder named 'crm-memberships' or similar, and read the main plugin PHP file to find the version declaration.Affected if The plugin is found and the version is 2.6 or lower (or no version is displayed, indicating an old installation).
-
Verify ntzcrm_changepassword AJAX action existsSend a POST request to /wp-admin/admin-ajax.php with action=ntzcrm_changepassword and a test email parameter (such as email: '[email protected]'), without providing any authentication tokens or nonces.Affected if The request returns a successful response or performs a password reset operation without requiring login or a valid nonce.
-
Verify ntzcrm_get_users endpoint is exposedSend a GET or POST request to /wp-admin/admin-ajax.php with action=ntzcrm_get_users, without any authentication headers or cookies.Affected if The response contains a list of user email addresses or subscriber data without requiring authentication.
-
Confirm lack of nonce verification on vulnerable endpointsInspect the source code of the CRM Memberships plugin (specifically the PHP handler functions for ntzcrm_changepassword and ntzcrm_get_users) and verify they do not call wp_verify_nonce, check_admin_referer, or verify_ajax_nonce.Affected if The code contains no nonce verification, capability checks (current_user_can), or authentication requirements (is_user_logged_in) for these AJAX actions.
A user is affected if the CRM Memberships plugin (version 2.6 or lower) is installed and the ntzcrm_changepassword or ntzcrm_get_users AJAX endpoints respond without authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to the latest version of the CRM Memberships plugin and implement proper nonce verification, capability checks, and authentication requirements on all AJAX endpoints. Restrict user enumeration to authenticated users only.
