Overview
Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key due to the default configuration of internal trust boundaries. An attacker can bypass security controls and access sensitive data or disrupt services within the mesh by manipulating x-envoy headers from external sources. This is only exploitable if the internal_address_config is empty or improperly configured.
