CVE-2016-7191
The Microsoft Azure Active Directory Passport (aka Passport-Azure-AD) library 1.x before 1.4.6 and 2.x before 2.0.1 for Node.js does not recognize the validateIssuer setting, which allows remote attackers to bypass authentication via a crafted token.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 29.4%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
