GHSA-gjcw-v447-2w7q
Forgeable Public/Private Tokens in jws
Quick fix
GHSA-gjcw-v447-2w7q — jws: upgrade to the fixed version with the command below.
npm install jws@3.0.0Details
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.
