The OneClick Chat to Order plugin for WordPress, developed by walterpinem, suffers from an authorization bypass vulnerability identified as CVE-2025-14270. The flaw exists in the wa_order_number_save_number_field function, which fails to properly verify whether a user has the necessary permissions to modify WhatsApp phone numbers associated with customer orders. This weakness allows any authenticated user with Editor-level or higher privileges to alter these phone numbers, effectively redirecting customer communications and orders to attacker-controlled endpoints. The vulnerability stems from CWE-862 (Missing Authorization), indicating that the plugin does not enforce adequate access control checks before performing sensitive operations. The CVSS 3.1 base score is 2.7, reflecting a low severity primarily because exploitation requires elevated privileges (Editor or above), no user interaction is needed, and the impact is limited to integrity (modification of phone numbers) without affecting confidentiality or availability. No public exploits have been reported, and no patches are currently available. This vulnerability could be leveraged in targeted attacks where an insider or compromised Editor account is used to intercept or manipulate customer orders, potentially causing financial loss or reputational damage. Given the plugin’s role in e-commerce workflows, the integrity of order routing is critical, and unauthorized changes could disrupt business operations or facilitate fraud. Organizations using this plugin should audit user roles, monitor changes to plugin settings, and apply principle of least privilege to reduce risk.

For European organizations, the primary impact of this vulnerability lies in the integrity of customer order processing and communication. Attackers with Editor-level access could redirect orders and customer messages to fraudulent WhatsApp numbers, leading to potential financial fraud, loss of customer trust, and disruption of sales processes. While the vulnerability does not directly expose sensitive data or cause service outages, the manipulation of order routing can result in undelivered or misdirected orders, impacting customer satisfaction and brand reputation. E-commerce businesses relying on this plugin for WhatsApp-based order communication are particularly at risk. Additionally, if attackers use this vector to conduct social engineering or phishing via redirected messages, it could escalate into broader security incidents. The low CVSS score may underestimate the business impact in sectors where order integrity is critical. European organizations must consider the potential for insider threats or compromised Editor accounts to exploit this vulnerability.

1. Immediately restrict Editor-level and higher privileges to trusted personnel only, enforcing strict role-based access control. 2. Monitor and audit changes to WhatsApp phone numbers configured in the OneClick Chat to Order plugin, using WordPress logging plugins or SIEM integration. 3. Disable or uninstall the OneClick Chat to Order plugin if it is not essential to business operations until a patch is released. 4. Implement multi-factor authentication (MFA) for all users with Editor or higher roles to reduce risk of account compromise. 5. Regularly review and update WordPress user roles and permissions to adhere to the principle of least privilege. 6. Stay informed about vendor updates and apply patches promptly once available. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect anomalous requests targeting plugin endpoints. 8. Educate staff about the risks of privilege misuse and encourage reporting of suspicious activity. 9. For organizations with development resources, review the plugin code to implement additional authorization checks as a temporary fix.
