CVE-2026-40702 CRITICAL

Published: 2026-06-25 | Last Modified: 2026-06-26 | Status: Deferred

Description

WebSocket endpoints lack proper authentication mechanisms, enabling attackers to impersonate charging stations. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.
