CVE-2026-24696 Details
Description
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 mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
A vulnerability exists in the WebSocket API of Everon OCPP Backends, all versions, due to a lack of rate limiting on authentication requests. This flaw could enable an attacker to perform denial-of-service attacks by disrupting or misdirecting legitimate charger telemetry, or to conduct brute-force attacks to gain unauthorized access. Successful exploitation could lead to unauthorized administrative control over affected charging stations or cause disruptions in charging services.
Everon has shut down their platform as of December 1, 2025.
