{"id":"DEBIAN-CVE-2026-59818","details":"etcd is a distributed key-value store for the data of a distributed system. Prior to 3.5.32 and 3.6.13, when etcd is configured with --listen-client-http-urls to split HTTP and gRPC client endpoints onto separate listeners, the --client-crl-file Certificate Revocation List is not enforced on the gRPC listener, allowing a client with a revoked certificate to authenticate successfully over gRPC. This issue is fixed in versions 3.5.32 and 3.6.13.","modified":"2026-08-27T23:06:13.977888099Z","published":"2026-07-08T21:16:54.503Z","upstream":["CVE-2026-59818"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-59818"}],"affected":[{"package":{"name":"etcd","ecosystem":"Debian:13","purl":"pkg:deb/debian/etcd?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.16-10","3.5.16-11","3.5.16-4","3.5.16-5","3.5.16-6","3.5.16-7","3.5.16-8","3.5.16-9","3.5.22-1","3.5.22-2","3.5.30-1~exp1","3.5.30-1~exp2","3.5.30-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59818.json"}},{"package":{"name":"etcd","ecosystem":"Debian:14","purl":"pkg:deb/debian/etcd?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.16-10","3.5.16-11","3.5.16-4","3.5.16-5","3.5.16-6","3.5.16-7","3.5.16-8","3.5.16-9","3.5.22-1","3.5.22-2","3.5.30-1~exp1","3.5.30-1~exp2","3.5.30-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59818.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
