| CVE-2026-47207 | Med | 0.00 | 6.5 | 0.00 | Jun 26, 2026 | Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.34.0 until 1.35.13, 1.36.9, 1.37.5, and 1.38.3, Envoy crashes if an ext_proc server sends a single gRPC message containing multiple, specially crafted ProcessingResponse messages. This… | ||
| CVE-2024-53271 | Hig | 0.00 | 7.1 | 0.01 | Dec 18, 2024 | Envoy is a cloud-native high-performance edge/middle/service proxy. In affected versions envoy does not properly handle http 1.1 non-101 1xx responses. This can lead to downstream failures in networked devices. This issue has been addressed in versions 1.31.5 and 1.32.3. Users… | ||
| CVE-2024-53270 | Hig | 0.00 | 7.5 | 0.01 | Dec 18, 2024 | Envoy is a cloud-native high-performance edge/middle/service proxy. In affected versions `sendOverloadError` is going to assume the active request exists when `envoy.load_shed_points.http1_server_abort_dispatch` is configured. If `active_request` is nullptr, only… | ||
| CVE-2024-53269 | Med | 0.00 | 4.5 | 0.01 | Dec 18, 2024 | Envoy is a cloud-native high-performance edge/middle/service proxy. When additional address are not ip addresses, then the Happy Eyeballs sorting algorithm will crash in data plane. This issue has been addressed in releases 1.32.2, 1.31.4, and 1.30.8. Users are advised to… | ||
| CVE-2024-32475 | Hig | 0.00 | 7.5 | 0.01 | Apr 18, 2024 | Envoy is a cloud-native, open source edge and service proxy. When an upstream TLS cluster is used with `auto_sni` enabled, a request containing a `host`/`:authority` header longer than 255 characters triggers an abnormal termination of Envoy process. Envoy does not gracefully… | ||
| CVE-2024-23327 | Hig | 0.00 | 7.5 | 0.01 | Feb 9, 2024 | Envoy is a high-performance edge/middle/service proxy. When PPv2 is enabled both on a listener and subsequent cluster, the Envoy instance will segfault when attempting to craft the upstream PPv2 header. This occurs when the downstream request has a command type of LOCAL and does… | ||
| CVE-2024-23325 | Hig | 0.00 | 7.5 | 0.01 | Feb 9, 2024 | Envoy is a high-performance edge/middle/service proxy. Envoy crashes in Proxy protocol when using an address type that isn’t supported by the OS. Envoy is susceptible to crashing on a host with IPv6 disabled and a listener config with proxy protocol enabled when it receives a… | ||
| CVE-2024-23324 | Hig | 0.00 | 8.6 | 0.01 | Feb 9, 2024 | Envoy is a high-performance edge/middle/service proxy. External authentication can be bypassed by downstream connections. Downstream clients can force invalid gRPC requests to be sent to ext_authz, circumventing ext_authz checks when failure_mode_allow is set to true. This issue… | ||
| CVE-2024-23323 | Med | 0.00 | 4.3 | 0.01 | Feb 9, 2024 | Envoy is a high-performance edge/middle/service proxy. The regex expression is compiled for every request and can result in high CPU usage and increased request latency when multiple routes are configured with such matchers. This issue has been addressed in released 1.29.1,… | ||
| CVE-2024-23322 | Hig | 0.00 | 7.5 | 0.01 | Feb 9, 2024 | Envoy is a high-performance edge/middle/service proxy. Envoy will crash when certain timeouts happen within the same interval. The crash occurs when the following are true: 1. hedge_on_per_try_timeout is enabled, 2. per_try_idle_timeout is enabled (it can only be done in… | ||
| CVE-2022-29228 | Hig | 0.00 | 7.5 | 0.01 | Jun 9, 2022 | Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT() in newer versions and corrupts memory on earlier versions.… | ||
| CVE-2022-29227 | Hig | 0.00 | 7.5 | 0.01 | Jun 9, 2022 | Envoy is a cloud-native high-performance edge/middle/service proxy. In versions prior to 1.22.1 if Envoy attempts to send an internal redirect of an HTTP request consisting of more than HTTP headers, there’s a lifetime bug which can be triggered. If while replaying the request… | ||
| CVE-2022-29226 | Cri | 0.00 | 10.0 | 0.01 | Jun 9, 2022 | Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the… | ||
| CVE-2022-29225 | Hig | 0.00 | 7.5 | 0.02 | Jun 9, 2022 | Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small… | ||
| CVE-2022-29224 | Med | 0.00 | 5.9 | 0.01 | Jun 9, 2022 | Envoy is a cloud-native high-performance proxy. Versions of envoy prior to 1.22.1 are subject to a segmentation fault in the GrpcHealthCheckerImpl. Envoy can perform various types of upstream health checking. One of them uses gRPC. Envoy also has a feature which can “hold”… | ||
| CVE-2022-23606 | Med | 0.00 | 4.4 | 0.01 | Feb 22, 2022 | Envoy is an open source edge and service proxy, designed for cloud-native applications.

| CVE-2022-21656 | Hig | 0.00 | 7.4 | 0.01 | Feb 22, 2022 | Envoy is an open source edge and service proxy, designed for cloud-native applications. The default_validator.cc implementation used to implement the default certificate validation routines has a "type confusion" bug when processing subjectAltNames. This processing allows, for… | ||
| CVE-2022-21655 | Hig | 0.00 | 7.5 | 0.01 | Feb 22, 2022 | Envoy is an open source edge and service proxy, designed for cloud-native applications. The envoy common router will segfault if an internal redirect selects a route configured with direct response or redirect actions. This will result in a denial of service. As a workaround… | ||
| CVE-2022-21654 | Hig | 0.00 | 7.4 | 0.01 | Feb 22, 2022 | Envoy is an open source edge and service proxy, designed for cloud-native applications.
