| CVE-2024-32475 | 0.00 | — | 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-2024-23322 | 0.00 | — | 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-2024-23323 | 0.00 | — | 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-2024-23324 | 0.00 | — | 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-2024-23325 | 0.00 | — | 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-2024-23327 | 0.00 | — | 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-2023-35944 | 0.00 | — | 0.01 | Jul 25, 2023 | Envoy is an open source edge and service proxy designed for cloud-native applications.

| CVE-2023-35943 | 0.00 | — | 0.01 | Jul 25, 2023 | Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, the CORS filter will segfault and crash Envoy when the `origin` header is removed and deleted between `decodeHeaders`and… | |||
| CVE-2023-35942 | 0.00 | — | 0.01 | Jul 25, 2023 | Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, gRPC access loggers using listener's global scope can cause a `use-after-free` crash when the listener is drained. Versions… | |||
| CVE-2023-35941 | 0.00 | — | 0.01 | Jul 25, 2023 | Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, a malicious client is able to construct credentials with permanent validity in some specific scenarios. This is caused by the… | |||
| CVE-2023-35945 | 0.00 | — | 0.01 | Jul 13, 2023 | Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy’s HTTP/2 codec may leak a header map and bookkeeping structures upon receiving `RST_STREAM` immediately followed by the `GOAWAY` frames from an upstream server. In nghttp2, cleanup of pending requests… | |||
| CVE-2023-27496 | 0.00 | — | 0.01 | Apr 4, 2023 | Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9, the OAuth filter assumes that a `state` query param is present on any response that looks like an OAuth redirect response. Sending… | |||
