{"id":"BIT-etcd-2026-59818","summary":"etcd: gRPC client listener does not enforce `--client-crl-file` certificate revocation","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.","aliases":["CVE-2026-59818","GHSA-3wh4-j44w-pg92"],"modified":"2026-09-08T08:47:09.970952874Z","published":"2026-07-14T15:42:36.975Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:etcd:etcd:*:*:*:*:*:go:*:*"]},"references":[{"type":"FIX","url":"https://github.com/etcd-io/etcd/commit/2308ce1578064641d4d67c40f0487309267d1bef"},{"type":"FIX","url":"https://github.com/etcd-io/etcd/commit/24838af5a53dd0245adced920e42a9bf0e7a267f"},{"type":"FIX","url":"https://github.com/etcd-io/etcd/commit/8221ae82bc25d4d55ca64382207b69be71038cbb"},{"type":"FIX","url":"https://github.com/etcd-io/etcd/pull/22007"},{"type":"FIX","url":"https://github.com/etcd-io/etcd/pull/22021"},{"type":"FIX","url":"https://github.com/etcd-io/etcd/pull/22025"},{"type":"ARTICLE","url":"https://github.com/etcd-io/etcd/releases/tag/v3.5.32"},{"type":"ARTICLE","url":"https://github.com/etcd-io/etcd/releases/tag/v3.6.13"},{"type":"ADVISORY","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-3wh4-j44w-pg92"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59818"}],"affected":[{"package":{"name":"etcd","ecosystem":"Bitnami","purl":"pkg:bitnami/etcd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.5.32"},{"introduced":"3.6.0"},{"fixed":"3.6.13"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/etcd/BIT-etcd-2026-59818.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.9.0"}
