CVE-2026-44383
Multiple connections to the backend using the same charging station ID are allowed, which could allow an attacker to deploy multiple instances of malicious OCPP clients to overwhelm the backend.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
