CVE-2026-25192
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWebSocket 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOCPP WebSocket endpoints lack authentication, allowing unauthenticated attackers to connect using known or discovered charging station identifiers and impersonate legitimate chargers. This enables issuance and reception of OCPP commands without verification, compromising backend systems and charging infrastructure control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Ctek Charge Portal installationLocate Ctek Charge Portal software in your environment - check for running processes, installed services, or web server configurations that host this applicationAffected if Ctek Charge Portal is present in your environment
-
Locate OCPP WebSocket endpointsScan your network or review application configuration to identify exposed OCPP WebSocket endpoints (typically ws:// or wss:// URIs on port 8080, 8443, or similar ports used by the Charge Portal)Affected if OCPP WebSocket endpoints are found exposed on the network
-
Test endpoint authentication requirementAttempt to establish a WebSocket connection to the OCPP endpoint using a known or guessed charging station identifier without providing credentialsAffected if Connection succeeds without any authentication challenge or credential prompt
-
Verify station identifier validationInspect the application's authentication and authorization configuration to determine how charging station identifiers are validated before accepting OCPP commandsAffected if No certificate-based, token-based, or other strong authentication mechanism is enforced on the WebSocket connection
Your environment is affected if Ctek Charge Portal is running with OCPP WebSocket endpoints accessible without requiring authentication or identity verification for charging station connections.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strong authentication (certificate-based or token-based) for all WebSocket connections and validate station identity before accepting commands. Add authorization checks ensuring only authenticated stations can execute privileged operations.
