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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200"],"references":["https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.4.md","https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.5.md","https://github.com/etcd-io/etcd/pull/15656","https://github.com/etcd-io/etcd/security/advisories/GHSA-3p4g-rcw5-8298","https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.4.md"],"products":["etcd:etcd"],"source":"nvd","synced_at":"2026-10-19T21:38:18.424950729+00:00"},"epss":{"cve":"CVE-2023-32082","score":0.00744,"percentile":0.54766,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3p4g-rcw5-8298","url":"https://osv.dev/vulnerability/GHSA-3p4g-rcw5-8298","summary":"etcd Key name can be accessed via LeaseTimeToLive API","modified":"2026-09-10T03:50:08.153551089Z","packages":[{"ecosystem":"Go","name":"github.com/etcd-io/etcd","purl":"pkg:golang/github.com/etcd-io/etcd","ranges":["<3.4.26"],"fixed":["3.4.26"]},{"ecosystem":"Go","name":"github.com/etcd-io/etcd","purl":"pkg:golang/github.com/etcd-io/etcd","ranges":[">=3.5.0 <3.5.9"],"fixed":["3.5.9"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
