CVE-2026-27652Network attack vector

Unauthenticated session hijacking via duplicate identifiers

Published Feb 26, 2026 · Updated Feb 26, 2026

Insufficient session expiration in CloudCharge all versions allows remote attackers to hijack charging-station sessions over WebSocket. The backend treats a predictable charging-station identifier as a unique session key but accepts concurrent endpoints with that key, letting the newest connection replace the legitimate station and receive its commands. No authentication or user interaction is required; exploitation enables station impersonation, backend-command disclosure, traffic suppression, or service interruption.
