CVE-2023-32082Network attack vector

Protected key-name disclosure via missing lease authorization

Published May 11, 2023 · Updated Jan 24, 2025

Information disclosure in etcd before 3.4.26 and 3.5.0 through 3.5.8 allows remote authenticated users to read protected key names. LeaseTimeToLive returns names for keys attached to a requested lease when Keys is true without first checking the caller's range permissions. Exposure requires enabled authentication, a known lease identifier, and protected keys attached to that lease; key values remain undisclosed.
