{"id":"UBUNTU-CVE-2023-32082","details":"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.","modified":"2026-07-02T18:00:42.564340926Z","published":"2023-05-11T20:15:00Z","upstream":["CVE-2023-32082"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-32082"},{"type":"REPORT","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-3p4g-rcw5-8298"},{"type":"REPORT","url":"https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.5.md"},{"type":"REPORT","url":"https://github.com/etcd-io/etcd/pull/15656"},{"type":"REPORT","url":"https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.4.md"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-32082"}],"affected":[{"package":{"name":"etcd","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/etcd?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.0+dfsg-2","2.2.1+dfsg-1","2.2.2+dfsg-1","2.2.2+dfsg-2","2.2.3+dfsg-1","2.2.5+dfsg-1","2.2.5+dfsg-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"etcd","binary_version":"2.2.5+dfsg-1ubuntu1"},{"binary_name":"golang-etcd-server-dev","binary_version":"2.2.5+dfsg-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-32082.json"}},{"package":{"name":"etcd","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/etcd?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.0-1","3.2.9+dfsg-2","3.2.9+dfsg-3","3.2.17+dfsg-1","3.2.17+dfsg-1ubuntu0.1~esm1","3.2.17+dfsg-1ubuntu0.1","3.2.17+dfsg-1ubuntu0.1+esm1","3.2.17+dfsg-1ubuntu0.1+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"etcd","binary_version":"3.2.17+dfsg-1ubuntu0.1+esm2"},{"binary_name":"etcd-client","binary_version":"3.2.17+dfsg-1ubuntu0.1+esm2"},{"binary_name":"etcd-server","binary_version":"3.2.17+dfsg-1ubuntu0.1+esm2"},{"binary_name":"golang-etcd-server-dev","binary_version":"3.2.17+dfsg-1ubuntu0.1+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-32082.json"}},{"package":{"name":"etcd","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/etcd?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.26+dfsg-3","3.2.26+dfsg-4","3.2.26+dfsg-6","3.2.26+dfsg-6ubuntu0.1","3.2.26+dfsg-6ubuntu0.2","3.2.26+dfsg-6ubuntu0.2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"etcd","binary_version":"3.2.26+dfsg-6ubuntu0.2+esm1"},{"binary_name":"etcd-client","binary_version":"3.2.26+dfsg-6ubuntu0.2+esm1"},{"binary_version":"3.2.26+dfsg-6ubuntu0.2+esm1","binary_name":"etcd-server"},{"binary_name":"golang-etcd-server-dev","binary_version":"3.2.26+dfsg-6ubuntu0.2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-32082.json"}},{"package":{"name":"etcd","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/etcd?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.25+dfsg-6","3.3.25+dfsg-7","3.3.25+dfsg-7ubuntu0.22.04.1","3.3.25+dfsg-7ubuntu0.22.04.1+esm1","3.3.25+dfsg-7ubuntu0.22.04.2","3.3.25+dfsg-7ubuntu0.22.04.2+esm1","3.3.25+dfsg-7ubuntu0.22.04.2+esm2","3.3.25+dfsg-7ubuntu0.22.04.2+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"3.3.25+dfsg-7ubuntu0.22.04.2+esm3","binary_name":"etcd"},{"binary_name":"etcd-client","binary_version":"3.3.25+dfsg-7ubuntu0.22.04.2+esm3"},{"binary_name":"etcd-server","binary_version":"3.3.25+dfsg-7ubuntu0.22.04.2+esm3"},{"binary_name":"golang-etcd-server-dev","binary_version":"3.3.25+dfsg-7ubuntu0.22.04.2+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-32082.json"}},{"package":{"name":"etcd","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/etcd?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.23-4ubuntu2","3.4.30-1","3.4.30-1build1","3.4.30-1ubuntu0.24.04.1","3.4.30-1ubuntu0.24.04.2","3.4.30-1ubuntu0.24.04.2+esm1","3.4.30-1ubuntu0.24.04.3","3.4.30-1ubuntu0.24.04.3+esm1","3.4.30-1ubuntu0.24.04.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.30-1ubuntu0.24.04.3+esm2","binary_name":"etcd-client"},{"binary_version":"3.4.30-1ubuntu0.24.04.3+esm2","binary_name":"etcd-server"},{"binary_name":"golang-etcd-server-dev","binary_version":"3.4.30-1ubuntu0.24.04.3+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-32082.json"}},{"package":{"name":"etcd","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/etcd?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.16-4"],"ecosystem_specific":{"binaries":[{"binary_version":"3.5.16-4","binary_name":"
