CVE-2026-25711Network attack vector

Unauthenticated session hijacking via identifier reuse

Published Feb 26, 2026 · Updated Feb 26, 2026

Insufficient session expiration in Chargemap chargemap.com allows remote attackers to hijack charging-station WebSocket sessions. The backend treats a predictable station identifier as a unique session key but accepts concurrent endpoints using that same identifier, assigning the session to the latest connection. No credentials or user interaction are required; an impostor can receive commands intended for the station, while repeated valid connections can interrupt service.
