Executive Summary

CVE-2025-14270 is a vulnerability in the OneClick Chat to Order WordPress plugin (version 1.0.9 and earlier) that allows an authorization bypass. Specifically, the plugin does not properly verify that a user is authorized to perform certain actions in the function wa_order_number_save_number_field.

This flaw enables authenticated users with Editor-level access or higher to modify WhatsApp phone numbers used by the plugin. By doing so, attackers can redirect customer orders and messages to phone numbers controlled by them.

The root cause is missing proper capability checks restricting management of WhatsApp numbers to administrators only. The plugin also lacked sufficient nonce verification to prevent unauthorized form submissions.

Impact Analysis

This vulnerability can impact you by allowing users with Editor-level permissions or higher to maliciously change the WhatsApp phone numbers used for order processing in the plugin.

As a result, customer orders and messages intended for your business could be redirected to attacker-controlled phone numbers, potentially leading to loss of orders, customer confusion, fraud, or data interception.

Because the attack requires authenticated users with elevated privileges, it represents a privilege escalation risk within your WordPress site.

Mitigation Strategies

The primary mitigation step is to update the OneClick Chat to Order plugin to version 1.1.0 or later, where the vulnerability has been fixed by enforcing proper authorization checks.

• Update the plugin to version 1.1.0, which restricts WhatsApp number management to users with the `manage_options` capability (typically administrators).
• Ensure that only trusted users have Administrator roles and that Editor-level users do not have unnecessary elevated permissions.
• Verify that nonce verification is enabled and functioning properly to protect against CSRF attacks on plugin forms.
• Audit existing WhatsApp number entries to confirm they have not been maliciously altered.

Following these steps will prevent unauthorized users from modifying WhatsApp numbers and redirecting customer orders or messages.
