CVE-2026-25778Network attack vector

Unauthenticated station impersonation via duplicate WebSocket sessions

Published Feb 27, 2026 · Updated Feb 27, 2026

Session hijacking in all versions of SWTCH Energy swtchenergy.com allows remote attackers to impersonate stations via duplicate WebSocket sessions. The backend treats a predictable charging-station identifier as the session identifier, accepts concurrent reuse, and lets the newest connection displace the legitimate station and receive its commands. No account or user interaction is required; successful shadowing exposes backend commands and can suppress or misroute legitimate station traffic.
