Authorization flaws in the Shopper admin panel allow authenticated users to escalate privileges and take over the entire system.

The application suffers from two authorization defects in the team settings module. Lack of proper mount authorization and improper permission gating allow a low-privilege user to modify roles and grant themselves administrative permissions, effectively taking over the RBAC system.

The CVSS score of 9.9 highlights the critical nature of this privilege escalation. An attacker can remove legitimate administrators and gain full control over the e-commerce backend, leading to complete data compromise, fraudulent order management, and reputational damage.

Immediate Action: Update to Shopper version 2.8.0 or later.

Proactive Monitoring: Audit user account changes, particularly those involving privilege modifications or role assignments, and review logs for suspicious administrative actions.

Compensating Controls: Implement secondary approval workflows for critical role changes and restrict access to team management settings to only the most trusted administrators.

Public Exploit Available: None

This vulnerability is a significant threat to organizational data. Administrators should update to version 2.8.0 immediately and review the current user list for any unauthorized administrative accounts that may have been created.
