CVE-2026-24696Network attack vector

Unauthenticated telemetry interruption via unlimited authentication requests

Published Mar 6, 2026 · Updated Mar 6, 2026

Improper authentication throttling in all versions of Everon api.everon.io allows remote attackers to interrupt charger telemetry. The WebSocket API accepts an unrestricted number of authentication requests because it applies no rate limit, allowing request floods to suppress or mis-route legitimate telemetry and unlimited credential guesses. No credentials or user interaction are required, but the hosted platform was shut down on December 1, 2025, limiting current exposure.
