Menulux Mobile App Authorization Bypass

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-2346

The vulnerability affects a mobile application, which typically resides on end-user devices rather than acting as a public-facing network service, gateway, or edge infrastructure. Mobile app components are generally not reachable directly via the public internet as standalone network-accessible services.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

Frequently asked questions

What is the Menulux Mobile App?

The Menulux Mobile App is a software product developed by Menulux Software Inc. It is typically used on end-user devices, such as smartphones or tablets, to interact with Menulux's business systems or service platforms. Because it functions as a client-side application, it serves as the interface between the user and the backend services, rather than acting as a standalone network server or gateway.

What does CWE-639 mean for CVE-2026-2346?

CWE-639 refers to an authorization bypass through a user-controlled key. In this context, it means the application incorrectly relies on information provided by the user—such as a key or identifier—to determine if they have permission to access specific data or features. Because the app does not properly verify this key, an attacker can manipulate it to trick the software into granting unauthorized access or administrative control.

How can an attacker trigger this vulnerability?

An attacker can exploit this flaw by manipulating the specific key the application uses for authorization. Because this is an authorization bypass, it does not require the attacker to have existing privileges or perform complex interactions. Note that this bug is specific to how the application processes these user-controlled keys; simply having the app installed or running does not inherently trigger the vulnerability without an attacker actively providing malicious input.

Is CVE-2026-2346 a risk to my network?

According to Halo Surface Signal, this vulnerability is considered very unlikely to be a direct network threat. Because the affected technology is a mobile application running on end-user devices, it does not typically act as a public-facing network service or edge infrastructure. Therefore, it is generally not reachable or exploitable directly via the public internet as a standalone service.

What should I do if I use this application?

If your organization uses this mobile app, start by auditing your mobile device management or inventory systems to identify all installed instances. Once you have a clear picture of deployment, determine which teams or business processes rely on the app. Coordinate with the relevant system owners to assess the data handled by the app and plan for necessary updates or risk mitigation steps provided by the vendor.
