CVE-2016-6298
The _Rsa15 class in the RSA 1.5 algorithm implementation in jwa.py in jwcrypto before 0.3.2 lacks the Random Filling protection mechanism, which makes it easier for remote attackers to obtain cleartext data via a Million Message Attack (MMA).

Does this matter?
Lower severity and a low EPSS score (2.25%). Track it; it rarely justifies an emergency change on its own.
