QID 983173

QID 983173: Nodejs (npm) Security Update for jwt-simple (GHSA-vgrx-w6rg-8fqf)

Affected versions of the `jwt-simple` package allow users to select what algorithm the server will use to verify a provided JWT. A malicious actor can use this behaviour to arbitrarily modify the contents of a JWT while still passing verification. For the common use case of the JWT, the end result is a complete authentication bypass with minimal effort.

## Recommendation

Update to version 0.3.1 or later.

Additionally, be sure to always specify an algorithm in calls to `.decode()`.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
