CVE-2026-54479
Received Received - Intake
Predictable Session Identifier in Charging Station Backend

Publication date: 2026-06-25

Last updated on: 2026-06-25

Assigner: ICS-CERT

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. 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.

Executive Summary

This vulnerability exists in the WebSocket backend that uses charging station identifiers to uniquely associate sessions. However, it allows multiple endpoints to connect using the same session identifier, resulting in predictable session identifiers.

Because of this, unauthorized users may be able to authenticate as other users or a malicious actor could cause a denial-of-service condition by overwhelming the backend with valid session requests.

Impact Analysis

This vulnerability can impact you by allowing unauthorized users to impersonate other users, potentially gaining access to restricted functions or data.

Additionally, it can enable attackers to launch denial-of-service attacks by flooding the backend with valid session requests, which could disrupt service availability.
