What is CVE-2023-32082?

etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.26 and 3.5.9, the 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). Versions 3.4.26 and 3.5.9 fix this issue. There are no known workarounds.

Affected Version(s)

etcd < 3.4.26 < 3.4.26

etcd >= 3.5.0, < 3.5.9 < 3.5.0, 3.5.9
