Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Envoy Gateway (github.com/envoyproxy/gateway) versions before 1.2.6 are affected. A user with access to a Kubernetes cluster where Envoy Gateway is installed can use a path traversal attack to reach the Envoy Admin interface on managed proxies, which can terminate the Envoy process and extract its configuration, possibly including confidential data. Upgrade to 1.2.6. Alternatively, apply a bootstrap config patch through the EnvoyProxy API that restricts access to the Prometheus stats endpoint only.
