Forgeable Public/Private Tokens in jws
8.7
HIGH
CVSS 3.1
Description
Affected versions of the `jws` 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 as a bearer token, the end result is a complete authentication bypass with minimal effort. ## Recommendation Update to version 3.0.0 or later.
