CVE-2025-24030
A user with access to the Kubernetes cluster can use a path traversal attack to execute Envoy Admin interface commands on proxies managed by any version of Envoy Gateway prior to 1.2.6.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. A user with access to the Kubernetes cluster can use a path traversal attack to execute Envoy Admin interface commands on proxies managed by any version of Envoy Gateway prior to 1.2.6. The admin interface can be used to terminate the Envoy process and extract the Envoy configuration (possibly containing confidential data). Version 1.2.6 fixes the issue. As a workaround, the `EnvoyProxy` API can be used to apply a bootstrap config patch that restricts access strictly to the prometheus stats endpoint. Find below an example of such a bootstrap patch.
