What is CVE-2016-7191?

The Microsoft Azure Active Directory Passport library, utilized in Node.js applications, suffers from a serious authentication bypass issue. Versions 1.x prior to 1.4.6 and 2.x prior to 2.0.1 do not properly recognize the 'validateIssuer' setting. This oversight enables remote attackers to exploit crafted tokens, bypassing standard authentication mechanisms and potentially gaining unauthorized access to sensitive application resources.
