envoyproxy/envoy: HTTP request with escaped slash characters can bypass Envoy's authorization mechanisms

An authorization bypass vulnerability was found in envoyproxy/envoy. An attacker can potentially craft an HTTP request that defines a certain pattern of escaped characters in the URI path such as %2F, %2f, %5C or %5c, allowing them to bypass the envoy authorization service. The highest threat fro...
