Charging Station Malicious Users Can Hijack Sessions
CVE-2026-27647
Summary
The software allows multiple users to share the same session ID, making it possible for malicious users to take over sessions and impersonate others, or disrupt the system by overwhelming it with requests. This can lead to unauthorized access or system downtime. To fix this, update the software to ensure that each session ID is unique and secure.

Original description
The WebSocket backend uses charging station identifiers to uniquely
associate sessions but allows multiple endpoints to connect using the
same session identifier. This implementation results in predictable
session identifiers and enables session hijacking or shadowing, where
the most recent connection displaces the legitimate charging station and
receives backend commands intended for that station. This vulnerability
may allow unauthorized users to authenticate as other users or enable a
malicious actor to cause a denial-of-service condition by overwhelming
the backend with valid session requests.
