CVE-2025-59398
The OCPP implementation in libocpp before 0.26.2 allows a denial of service (EVerest crash) via JSON input larger than 255 characters, because a CiString<255> object is created with StringTooLarge set to Throw.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
