| CVE ID | CVSS Score | Severity | Description |
|---|---|---|---|
| CVE-2026-69658 | 9.8 | critical |
MQTT credentials and control traffic are transmitted in cleartext, exposing sensitive information to network-level attackers. This may enable unauthorized device impersonation and disruption of messaging functions.
|
| CVE-2026-75548 | 5.4 | medium |
The affected Ebyte device web management interface does not restrict the interface from being rendered within an external frame. An unauthenticated remote attacker could use a crafted webpage to mislead an authenticated administrator into initiating unintended configuration changes or disruptive actions.
|
| CVE-2026-73125 | 9.8 | critical |
Ebyte device web management interface does not consistently enforce authentication before granting access to administrative functionality. An unauthenticated remote attacker could access sensitive configuration information, modify device settings, or disrupt availability.
|
| CVE-2026-76179 | 9.8 | critical |
An improper protection of authentication tokens vulnerability exists in certain Ebyte gateway products. Authentication tokens used by the web management interface are insufficiently protected during client-side session handling, which may allow an attacker with access to exposed session information to obtain and reuse a valid token. Successful exploitation could allow an attacker to impersonate an authenticated user and gain unauthorized access to device management functionality.
|
| CVE-2026-71187 | 9.8 | critical |
Ebyte device relies on client side authentication logic that can be reproduced by unauthenticated users. An attacker may generate valid authentication requests and bypass authentication to obtain administrative access to the device.
|
| CVE-2026-75814 | 8.8 | high |
Ebyte device does not adequately verify the origin or authenticity of requests submitted to the web management interface. An unauthenticated remote attacker could persuade an authenticated administrator to visit a crafted page, causing unauthorized configuration changes or a disruption of device availability.
|
| CVE-2026-76940 | 7.5 | high |
The affected Ebyte device does not restrict repeated authentication attempts through rate limiting or account lockout mechanisms. This could allow an attacker to perform automated authentication attacks against deployments that rely on password based authentication.
|
| CVE-2026-75813 | 7.5 | high |
Certain configuration endpoints may lack proper server-side authorization checks, allowing unauthorized users to access or modify sensitive device settings. This could result in full compromise of device functionality.
|
| CVE-2026-73839 | 4.6 | medium |
Administrative credentials may be exposed in plaintext within the Ebyte device's management interface, increasing the risk of credential compromise through visual or remote observation. This undermines the confidentiality of device access.
|
| CVE-2026-73809 | 7.5 | high |
A cleartext transmission of sensitive information vulnerability exists in certain Ebyte gateway products. The web management interface does not adequately protect sensitive communications using transport-layer encryption. An attacker with access to network traffic could intercept authentication or session-related information transmitted between a user and the affected device. Successful exploitation could result in disclosure of sensitive information and unauthorized access to device management functionality.
|
| CVE-2026-76945 | 7.5 | high |
The affected Ebyte device relies on client-managed authentication tokens without sufficient server-side validation. An attacker may replay or manipulate authentication tokens to gain unauthorized access to administrative functionality.
