CVE-2025-14270: OneClick Chat to Order Auth Bypass Flaw

CVE-2025-14270 Overview

The OneClick Chat to Order plugin for WordPress contains an authorization bypass vulnerability in versions up to and including 1.0.9. The vulnerability exists due to improper verification of user authorization in the wa_order_number_save_number_field function. This flaw allows authenticated attackers with Editor-level access or above to modify WhatsApp phone numbers used by the plugin, potentially redirecting customer orders and messages to attacker-controlled phone numbers.

Critical Impact

Authenticated attackers can redirect customer communications and orders to malicious phone numbers, enabling potential fraud and data theft.

Affected Products

• OneClick Chat to Order WordPress Plugin versions up to and including 1.0.9

Technical Details for CVE-2025-14270

Vulnerability Analysis

This authorization bypass vulnerability (CWE-862: Missing Authorization) stems from inadequate access control checks within the OneClick Chat to Order plugin. The vulnerable function wa_order_number_save_number_field fails to properly validate whether the requesting user has the appropriate permissions to modify plugin settings. While the plugin does require authentication, it does not enforce proper capability checks beyond basic authentication, allowing users with Editor-level privileges to perform actions that should be restricted to higher-privileged administrators.

The vulnerability is exploitable over the network and requires no user interaction, though it does necessitate high privileges (Editor-level access). The impact is limited to integrity concerns, as attackers can only modify WhatsApp phone number settings without directly accessing confidential data or disrupting service availability.

Root Cause

The root cause of this vulnerability is the absence of proper authorization checks in the wa_order_number_save_number_field function located in the includes/multiple-numbers.php file. The plugin fails to implement WordPress capability checks (such as current_user_can()) or nonce verification before processing requests to modify WhatsApp phone numbers. This violates the principle of least privilege and allows any authenticated user with Editor-level access to make changes that should be restricted to site administrators.

Attack Vector

The attack vector is network-based and requires authenticated access at the Editor level or higher. An attacker with compromised Editor credentials or a malicious insider with Editor access can exploit this vulnerability by sending crafted requests to the vulnerable function. The attack flow involves:

1. Authenticating to the WordPress site with Editor-level or higher privileges
2. Sending a request to the wa_order_number_save_number_field function to modify the WhatsApp phone numbers
3. Replacing legitimate business phone numbers with attacker-controlled numbers
4. Intercepting customer orders and messages intended for the legitimate business

The vulnerable code can be examined in the WordPress Plugin Code Reference. For additional technical analysis, refer to the Wordfence Vulnerability Analysis.

Detection Methods for CVE-2025-14270

Indicators of Compromise

• Unexpected changes to WhatsApp phone numbers configured in the OneClick Chat to Order plugin settings
• Audit log entries showing modifications to plugin settings by users who should not have such access
• Customer reports of order communications being sent to unfamiliar phone numbers
• Suspicious activity from Editor-level accounts accessing plugin configuration endpoints

Detection Strategies

• Implement WordPress activity logging to monitor changes to plugin settings, particularly the WhatsApp phone number fields
• Configure alerts for any modifications to OneClick Chat to Order plugin settings by non-administrator users
• Review WordPress user access logs for Editor accounts making unexpected configuration changes
• Deploy Web Application Firewall (WAF) rules to monitor requests to the vulnerable endpoint

Monitoring Recommendations

• Enable comprehensive audit logging for all WordPress plugin configuration changes
• Regularly review the configured WhatsApp phone numbers in the plugin to ensure they haven't been tampered with
• Monitor for anomalous patterns of requests to WordPress admin endpoints from Editor-level accounts
• Implement change management procedures requiring verification before phone number updates take effect

How to Mitigate CVE-2025-14270

Immediate Actions Required

• Update the OneClick Chat to Order plugin to version 1.0.10 or later immediately
• Review and verify all WhatsApp phone numbers currently configured in the plugin
• Audit Editor-level user accounts and remove unnecessary elevated privileges
• Review WordPress activity logs for any suspicious configuration changes prior to patching

Patch Information

The vulnerability has been addressed in the OneClick Chat to Order plugin. The fix can be reviewed in the WordPress Plugin Changeset. Plugin administrators should update to the latest version through the WordPress plugin dashboard. The patch adds proper capability checks and nonce verification as recommended in the WordPress User Capabilities Security documentation.

Workarounds

• Restrict Editor-level access to only trusted users who absolutely require it until the plugin can be patched
• Temporarily disable the OneClick Chat to Order plugin if not critical to business operations
• Implement additional access controls at the server level to restrict access to the vulnerable endpoint
• Configure a Web Application Firewall to block or alert on requests to the affected function

# Configuration example
# Verify plugin version and update via WP-CLI
wp plugin list --name=oneclick-whatsapp-order --fields=name,version,update_version
wp plugin update oneclick-whatsapp-order

# Audit recent changes to options related to the plugin
wp db query "SELECT option_name, option_value FROM wp_options WHERE option_name LIKE '%oneclick%whatsapp%'"
