TL;DR

Affected versions of this package return an incorrect status code. When a refresh token has expired, been revoked, cannot be decrypted, or does not belong to the correct client. In the patch version, the server correctly issues an invalid_grant error with a HTTP 400 response but in previous versions, the server incorrectly issued an invalid_request error and a HTTP 401 response. This issue has been resolved to ensure the correct handling of token-related errors and improve error reporting consistency.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
