  5. CVE-2026-33413 etcd: Authorization bypasses in multiple APIs

    Published
    HighCVSS 8.8 EPSS 0.26%

    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 parti...

  6. CVE-2026-33343 etcd: Nested etcd transactions bypass RBAC authorization checks

    Published
    MediumCVSS 6.5 EPSS 0.22%

    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, an authenticated user with RBAC restricted permissions on key ranges can use nested transactions to bypass all key-level authorization. This allows any authent...

  7. CVE-2023-32082 etcd key name can be accessed via LeaseTimeToLive API

    Published
    MediumCVSS 4.3 EPSS 0.74%

    etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.26 and 3.5.9, the LeaseTimeToLive API allows access to key names (not value) associated to a lease when Keys parameter is true, even a user doesn't have read permission to the keys....

  8. CVE-2020-15136 Improper authentication in etcd

    Published
    MediumCVSS 6.5 EPSS 1.7%

    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 di...

  9. CVE-2020-15114 Denial of Service in etcd

    Published
    HighCVSS 7.7 EPSS 1.1%

    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...

  10. CVE-2020-15115 No minimum password length in etcd

    Published
    HighCVSS 7.5 EPSS 1.3%

    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.

  11. CVE-2020-15112 Improper Input Validation in etcd

    Published
    MediumCVSS 6.5 EPSS 1.3%

    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 do...

  12. CVE-2020-15113 Improper Preservation of Permissions in etcd

    Published
    HighCVSS 7.1 EPSS 0.22%

    In etcd before versions 3.3.23 and 3.4.10, certain directory paths are created (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.M...

  13. CVE-2020-15106 Improper Input Validation in etcd

    Published
    MediumCVSS 6.5 EPSS 1.3%

    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...
