Details

### Impact
LeaseTimeToLive API allows access to key names (not value) associated to a lease when `Keys` parameter is true, even a user doesn't have read permission to the keys. The impact is limited to a cluster which enables auth (RBAC).
### Patches
< v3.4.26 and < v3.5.9 are affected.
### Workarounds
No.
