QID 981838

QID 981838: Go (go) Security Update for github.com/dgrijalva/jwt-go (GHSA-w73w-5m7g-f7qc)

jwt-go allows attackers to bypass intended access restrictions in situations with []string{} for m["aud"] (which is allowed by the specification). Because the type assertion fails, "" is the value of aud. This is a security problem if the JWT token is presented to a service that lacks its own audience check. There is no patch available and users of jwt-go are advised to migrate to [golang-jwt](https://github.com/golang-jwt/jwt) at version 3.2.1

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
