This deficiency enables an attacker to either flood the service with repeated authentication attempts, causing legitimate charger telemetry to be suppressed or mis\u2011routed, or to brute\u2011force credentials in pursuit of unauthorized access.

The EPSS score is below 1\u202f% and the issue is not listed in CISA\u2019s KEV catalog, indicating that large\u2011scale exploitation is unlikely at present. However, the lack of rate limiting means that an attacker who can reach the WebSocket endpoint\u2014most plausibly from the Internet via the car\u2011charger\u2019s network interface\u2014could launch a denial\u2011of\u2011service or brute\u2011force campaign.
