There is no fixed version for RHEL:10 etcd.

NVD Description

Note: Versions mentioned in the description apply only to the upstream etcd package and not the etcd package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

jwt-go before 4.0.0-preview1 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.
