| CVE-2025-46821 | 0.00 | — | 0.00 | May 7, 2025 | Envoy is a cloud-native edge/middle/service proxy. Prior to versions 1.34.1, 1.33.3, 1.32.6, and 1.31.8, Envoy's URI template matcher incorrectly excludes the `*` character from a set of valid characters in the URI path. As a result URI path containing the `*` character will not… | |||
| CVE-2025-30157 | 0.00 | — | 0.00 | Mar 21, 2025 | Envoy is a cloud-native high-performance edge/middle/service proxy. Prior to 1.33.1, 1.32.4, 1.31.6, and 1.30.10, Envoy's ext_proc HTTP filter is at risk of crashing if a local reply is sent to the external server due to the filter's life time issue. A known situation is the… | |||
| CVE-2024-53271 | 0.00 | — | 0.01 | Dec 18, 2024 | Envoy is a cloud-native high-performance edge/middle/service proxy.

This issue arises due to Envoy's… | |||
| CVE-2024-45807 | 0.00 | — | 0.01 | Sep 19, 2024 | Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy's 1.31 is using `oghttp` as the default HTTP/2 codec, and there are potential bugs around stream management in the codec. To resolve this Envoy will switch off the `oghttp2` by default. The impact of this… | |||
| CVE-2024-45808 | 0.00 | — | 0.00 | Sep 19, 2024 | Envoy is a cloud-native high-performance edge/middle/service proxy.
