AI Analysis
Technical Summary
The yshop-crm product through version 2.1.3 fails to enforce authorization on the sendSms and sendMail endpoints within the CrmCustomerController. This flaw permits any authenticated back-office user to invoke POST requests to /admin-api/crm/customer/send-sms and /admin-api/crm/customer/send-mail with arbitrary customerIds, templateCode, and templateParams. As a result, unauthorized messages can be sent through the organization's SMS and email channels to arbitrary customers.
Potential Impact
An attacker with authenticated back-office access can send unauthorized SMS and email messages to any customer, potentially leading to phishing, spam, or reputational damage. The vulnerability does not require user interaction and has a network attack vector with low attack complexity. The CVSS 4.0 base score is 5.3, indicating medium severity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict back-office user permissions to trusted personnel only and monitor usage of the sendSms and sendMail endpoints to detect anomalous activity.
