summary: EnvoyProxy Envoy Missing HTTP URL path normalization
description: |-
    Envoy 1.9.0 and before does not normalize HTTP URL paths. A remote attacker may
    craft a relative path, e.g., `something/../admin`, to bypass access control,
    e.g., a block on `/admin`. A backend server could then interpret the
    non-normalized path and provide an attacker access beyond the scope provided for
    by the access control policy.
