CVE-2016-6298 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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).. EPSS estimates a 2.23% chance of exploitation in the next 30 days.
