CVE-2026-27764Network attack vector

Unauthenticated session hijacking via identifier reuse

Published Mar 6, 2026 · Updated Mar 6, 2026

Insufficient session expiration in all versions of MVM Mobiliti Kft. e-mobi.hu allows remote attackers to hijack charging-station sessions. The WebSocket backend accepts simultaneous endpoints sharing a predictable charging-station identifier and assigns the session to the newest connection. No authentication or user interaction is required; the newest connection receives commands for the legitimate station and can interrupt service.
