{"id":"AZL-92141","summary":"CVE-2026-59818 affecting package etcd for versions less than 3.5.33-1","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":"2026-08-28T17:48:06.759312480Z","published":"2026-07-08T21:16:54Z","upstream":["CVE-2026-59818"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59818"}],"affected":[{"package":{"name":"etcd","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/etcd"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.33-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-92141.json"}}],"schema_version":"1.9.0"}
