CRITICAL
GHSA-vgrx-w6rg-8fqf
Forgeable Public/Private Tokens in jwt-simple
Quick fix
GHSA-vgrx-w6rg-8fqf — jwt-simple: upgrade to the fixed version with the command below.
npm install jwt-simple@0.3.1Details
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()`.
