Envoy Gateway: Authentication Bypass via Improper Input Validation in EnvoyExtensionPolicy Lua Allows Secret Disclosure

Impact The toabsolutenormalizedpath function security.lua:28-43 does not collapse redundant path separators // → /. On Linux, //etc/passwd is equivalent to /etc/passwd POSIX path semantics, but iscriticalpath fails to match the double-slash variant because //etc/passwd does not start with /etc/...
