CVE-2023-49955
It does not validate the length of the chargePointVendor field in a BootNotification message, potentially leading to server instability and a denial of service when processing excessively large inputs.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
