CVE-2026-97212

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.

Affected Software

Weaknesses

• CWE-613: CWE-613

Workarounds

Monta states that they are actively working to increase adoption of authenticated connections across their network and to deprecate unauthenticated access on a rolling basis. Monta states that they provide support for OCPP 1.6 Security Profile 2 (HTTP Basic Auth with TLS) and encourage operators to enable it. Monta states that they have implemented rate limiting and automated connection throttling at the WebSocket layer. Connections exhibiting abusive patterns, including rapid reconnection, ID brute-forcing behavior, or excessive command volume, are automatically identified and blocked. Monta states that their platform handles duplicate connection attempts per the OCPP specification, where a new authenticated connection supersedes an existing session for the same station ID.
