Configured global Request::get() validator:

# config.yml

    - { resource: parameters.yml }

services:
# (...)

    # Validate or sanitize every Request::get() call
    request_validator: 
        class: (...)
        arguments: [ '%request_validator_config%' ]
        tags: [{ name: kernel.event_listener, event: request.post_get}]

    # Replace every Request ParameterBag object with proxied one
    request_parameter_bag_replace: 
        class: (...)
        tags: [{ name: kernel.event_listener, event: kernel.request, priority: 140}]

    # ParameterBag proxy for get() and quote() methods dispatching
    # request.pre_get and request.post_get events on ParameterBag::get() 
    # request.pre_quote and request.post_quote on ParameterBag::quote()
