| CVE-2021-28235 | Cri | 0.64 | 9.8 | 0.02 | Apr 4, 2023 | Authentication vulnerability found in Etcd-io v.3.4.10 allows remote attackers to escalate privileges via the debug function. | ||
| CVE-2026-73500 | Hig | 0.50 | — | 0.00 | Aug 12, 2026 | etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.5.33, 3.6.14, and 3.7.1, a network attacker who can reach an etcd TLS listener can open many TCP connections and never send a ClientHello. In client/pkg/transport/listener_tls.go,… | ||
| CVE-2026-33413 | Hig | 0.50 | 8.8 | 0.00 | Mar 26, 2026 | etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.42, 3.5.28, and 3.6.9, unauthorized users may bypass authentication or authorization checks and call certain etcd functions in clusters that expose the gRPC API to untrusted or… | ||
| CVE-2020-15114 | Hig | 0.50 | 7.7 | 0.01 | Aug 6, 2020 | In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a… | ||
| CVE-2018-16886 | Hig | 0.46 | 8.1 | 0.04 | Jan 14, 2019 | etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication issue when role-based access control (RBAC) is used and client-cert-auth is enabled. If an etcd client server TLS certificate contains a Common Name (CN) which matches a valid… | ||
| CVE-2022-34038 | Hig | 0.42 | 7.5 | 0.01 | Aug 22, 2023 | Etcd v3.5.4 allows remote attackers to cause a denial of service via function PageWriter.write in pagewriter.go. NOTE: the vendor's position is that this is not a vulnerability. | ||
| CVE-2020-15136 | Med | 0.42 | 6.5 | 0.02 | Aug 6, 2020 | In ectd before versions 3.4.10 and 3.3.23, gateway TLS authentication is only applied to endpoints detected in DNS SRV records. When starting a gateway, TLS authentication will only be attempted on endpoints identified in DNS SRV records for a given domain, which occurs in the… | ||
| CVE-2026-73499 | Hig | 0.39 | — | 0.00 | Aug 12, 2026 | etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.5.33, 3.6.14, and 3.7.1, a user granted READ permission on a single exact key can use the Watch gRPC API with clientv3.WithFromKey() to receive watch events for every key… | ||
| CVE-2020-15115 | Med | 0.38 | 5.8 | 0.01 | Aug 6, 2020 | etcd before versions 3.3.23 and 3.4.10 does not perform any password length validation, which allows for very short passwords, such as those with a length of one. This may allow an attacker to guess or brute-force users' passwords with little computational effort. | ||
| CVE-2026-59818 | Med | 0.35 | 6.5 | 0.00 | Jul 8, 2026 | 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… | ||
| CVE-2020-15112 | Med | 0.35 | 6.5 | 0.01 | Aug 5, 2020 | In etcd before versions 3.3.23 and 3.4.10, it is possible to have an entry index greater then the number of entries in the ReadAll method in wal/wal.go. This could cause issues when WAL entries are being read during consensus as an arbitrary etcd consensus participant could go… | ||
| CVE-2020-15106 | Med | 0.35 | 6.5 | 0.01 | Aug 5, 2020 | In etcd before versions 3.3.23 and 3.4.10, a large slice causes panic in decodeRecord method. The size of a record is stored in the length field of a WAL file and no additional validation is done on this data. Therefore, it is possible to forge an extremely large frame size that… | ||
| CVE-2023-0296 | Med | 0.34 | 5.3 | 0.00 | Jan 17, 2023 | The Birthday attack against 64-bit block ciphers flaw (CVE-2016-2183) was reported for the health checks port (9979) on etcd grpc-proxy component. Even though the CVE-2016-2183 has been fixed in the etcd components, to enable periodic health checks from kubelet, it was necessary… | ||
