CVE-2026-25851
Critical · 9.8
CWE-306 Feb 26, 2026
Chargemap chargemap.com Missing Authentication for Critical Function
WebSocket endpoints lack proper authentication mechanisms, enabling
attackers to perform unauthorized station impersonation and manipulate
data sent to the backend. An unauthenticated attacker can connect to the
OCPP WebSocket endpoint using a known or discovered charging station
identifier, then issue or receive OCPP commands as a legitimate charger.
Given that no authentication is required, this can lead to privilege
escalation, unauthorized control of charging infrastructure, and
corruption of charging network data reported to the backend.
CVE-2026-25711

CWE-613 Feb 26, 2026
Chargemap chargemap.com Insufficient Session Expiration
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 and enables session hijacking or shadowing, where
the most recent connection displaces the legitimate charging station and
receives backend commands intended for that station. 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.
CVE-2026-20792
Critical · 9.8
CWE-307 Feb 26, 2026
Chargemap chargemap.com Improper Restriction of Excessive Authentication Attempts
The WebSocket Application Programming Interface lacks restrictions on
the number of authentication requests. This absence of rate limiting may
allow an attacker to conduct denial-of-service attacks by suppressing
or misrouting legitimate charger telemetry, or conduct brute-force
attacks to gain unauthorized access.

Chargemap chargemap.com Insufficiently Protected Credentials
Charging station authentication identifiers are publicly accessible via web-based mapping platforms.
