Hi,
The following vulnerability was published for google-oauth-client-java.
CVE-2021-22573[0]:
| The vulnerability is that IDToken verifier does not verify if token is
| properly signed. Signature verification makes sure that the token's
| payload comes from valid provider, not from someone else. An attacker
| can provide a compromised token with custom payload. The token will
| pass the validation on the client side. We recommend upgrading to
| version 1.33.3 or above
> The spec requires to validate the signature of ID token for apps that
> cannot guarantee TLS communication, which is the case for this library.
> This library initiates a local server that can run on any client machine
> without TLS support. So, it is critical to validate the signature,
> before trusting the claims of an ID token, which can be received from
> a malicious service provider.
Fixed in upstream release 1.33.3
