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 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
