{"id":"DEBIAN-CVE-2026-44283","details":"etcd is a distributed key-value store for the data of a distributed system. Prior to 3.4.44, 3.5.30, and 3.6.11, a vulnerability in etcd allows read access via PrevKv, or lease attachment in Put requests within transaction operations, to bypass RBAC authorization checks. An authenticated user without sufficient read or lease-related permissions may be able to access unauthorized data or attach leases by invoking transaction operations with these features enabled. This vulnerability is fixed in 3.4.44, 3.5.30, and 3.6.11.","modified":"2026-09-01T16:06:44.527895611Z","published":"2026-05-14T18:16:49.650Z","upstream":["CVE-2026-44283"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-44283"}],"affected":[{"package":{"name":"etcd","ecosystem":"Debian:12","purl":"pkg:deb/debian/etcd?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.23-4","3.4.23-5","3.4.23-6","3.4.30-1","3.4.30-2","3.4.30-3","3.5.15-1","3.5.15-2","3.5.15-3","3.5.15-4","3.5.15-5","3.5.15-6","3.5.15-7","3.5.16-1","3.5.16-10","3.5.16-11","3.5.16-2","3.5.16-3","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","3.5.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44283.json"}},{"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-2026-44283.json"}},{"package":{"name":"etcd","ecosystem":"Debian:14","purl":"pkg:deb/debian/etcd?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.16-11"}]}],"versions":["3.5.16-10","3.5.16-4","3.5.16-5","3.5.16-6","3.5.16-7","3.5.16-8","3.5.16-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44283.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:L/I:N/A:N"}]}
