# CVE-2026-76179

> 9.3 CRITICAL · 🧪 PoC

## Beschreibung

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.
