CVE-2026-114387 in Shopper
Summary
by MITRE • 10/21/2026
Shopper from 2.0.0 before 2.6.0 contains a missing authorization vulnerability that allows admin-panel users holding only access_dashboard to create administrators and grant permissions. Attackers can call CreateTeamMember::store() or Permissions::togglePermission() directly over /livewire/update to create admin accounts and escalate to full administrator.

The identified vulnerability in Shopper versions prior to 2.6.0 represents a critical failure in access control mechanisms, specifically classified under CWE-862 as Missing Authorization. This flaw exists within the application's administrative panel functionality, where role-based permissions are not correctly enforced during specific API interactions. The core issue stems from an insufficient check on user privileges when executing actions that modify system configuration or user roles. While the application intends to restrict certain high-level operations to users with full administrator rights, it inadvertently allows users possessing only the access_dashboard permission to perform these restricted actions by directly invoking backend methods without proper validation of their actual role level.
The technical exploitation vector involves interacting with Livewire endpoints, specifically targeting the CreateTeamMember::store() and Permissions::togglePermission() functions via the /livewire/update route. In a properly secured implementation, any request attempting to create a new team member or toggle administrative permissions should first verify that the initiating user holds the necessary admin privileges. However, due to this missing authorization check, an authenticated attacker with limited dashboard access can craft HTTP requests to these endpoints. By manipulating the payload sent through the Livewire update mechanism, the attacker can supply data that creates a new user account and assigns it elevated permissions, effectively bypassing the intended security boundaries of the application's role hierarchy.
The operational impact of this vulnerability is severe, as it facilitates privilege escalation from a low-privileged dashboard user to a full system administrator. Once an attacker successfully exploits this flaw, they gain unrestricted access to all administrative features within Shopper. This includes the ability to manage products, view sensitive customer data, modify site configurations, and potentially install malicious extensions or plugins if such functionality is exposed through the admin panel. The compromise of these privileges undermines the integrity and confidentiality of the entire e-commerce platform, allowing for potential data breaches, financial fraud, or complete defacement of the website infrastructure.
To mitigate this risk, immediate action must be taken to upgrade Shopper to version 2.6.0 or later, where this authorization logic has been corrected. For organizations unable to patch immediately due to operational constraints, a temporary workaround involves restricting direct access to the /livewire/update endpoint at the web server level for users who do not possess full administrative roles. Additionally, implementing strict input validation and ensuring that all role-checking middleware is applied consistently across Livewire components can help prevent similar bypasses in other parts of the application. Security teams should also audit existing user accounts to ensure no unauthorized administrators were created during the window of vulnerability exposure. This incident aligns with ATT&CK technique T1078, Valid Accounts, as it involves using legitimate credentials to escalate privileges within a system due to flawed access control policies.
