CVE-2022-39388 WRITEUP HIGH WRITEUP
Istio 1.15.0-1.15.2 and 1.15.0-beta.0-1.15.3 - Incorrect Authorization via Workload Identity Impersonation
Istio is an open platform to connect, manage, and secure microservices. In versions on the 1.15.x branch prior to 1.15.3, a user can impersonate any workload identity within the service mesh if they have localhost access to the Istiod control plane. Version 1.15.3 contains a patch for this issue. There are no known workarounds.

CVE-2024-39305 WRITEUP MEDIUM WRITEUP
Envoy < 1.30.4, 1.29.7, 1.28.5, 1.27.7 - Use-After-Free in Route Hash Policy Cookie Attributes
Envoy is a cloud-native, open source edge and service proxy. Prior to versions 1.30.4, 1.29.7, 1.28.5, and 1.27.7. Envoy references already freed memory when route hash policy is configured with cookie attributes. Note that this vulnerability has been fixed in the open as the effect would be immediately apparent if it was configured. Memory allocated for holding attribute values is freed after configuration was parsed. During request processing Envoy will attempt to copy content of de-allocated memory into request cookie header. This can lead to arbitrary content of Envoy's memory to be sent to the upstream service or abnormal process termination. This vulnerability is fixed in Envoy versions v1.30.4, v1.29.7, v1.28.5, and v1.27.7. As a workaround, do not use cookie attributes in route action hash policy.
