NVD Description

Note: Versions mentioned in the description apply only to the upstream k9s package and not the k9s package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.
