CVE-2026-20792
This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or misrouting legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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 misrouting legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
