CVE-2026-27647Network attack vector

Unauthenticated session hijacking via duplicate station identifiers

Published Feb 27, 2026 · Updated Feb 27, 2026

Insufficient session expiration in all versions of Mobility46 mobility46.se allows remote attackers to hijack charging-station WebSocket sessions. The backend treats a charging station identifier as a unique session key but accepts concurrent endpoints using the same predictable identifier, assigning the session to the newest connection. Exploitation requires a valid or guessed station identifier, displaces the legitimate charger, exposes backend commands, and can interrupt service through request flooding.
