Details

Forgeable Public/Private Tokens in jwt-simple 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()`.
