CVE-2026-40702 (GCVE-0-2026-40702)
Vulnerability from cvelistv5 – Published: 2026-06-25 20:59 – Updated: 2026-06-26 13:21

Title
EVoke Systems EVoke CSMS Missing Authentication for Critical Function
Summary
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.

CVE-2026-54479 (GCVE-0-2026-54479)
Vulnerability from cvelistv5 – Published: 2026-06-25 20:56 – Updated: 2026-06-26 13:53
VLAI
Title
EVoke Systems EVoke CSMS Insufficient Session Expiration
Summary
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
