Who assigns CVSS?
NVD analysts
In such situations, NVD analysts assign CVSS scores using a worst case approach. Thus, if a vendor provides no details about a vulnerability, NVD will score that vulnerability as a 10.0 (the highest rating).
Is Jackson faster than Gson?
Gson is the slowest at deserializing JSONs. It’s almost twice as slow as Moshi and JSONObject and slower than Jackson by more than twice in that regard. Another thing to take note at is Gson is the only library producing larger JSON Strings than the other solutions.
