Envoy ext auth can be bypassed when Proxy protocol filter sets invalid UTF-8 metadata
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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 has been addressed in released 1.29.1, 1.28.1, 1.27.3, and 1.26.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.
