Problem/Motivation

To fix https://www.drupal.org/sa-core-2018-002 we introduced the \Drupal\Core\Security\RequestSanitizer. We added functionality to it in https://www.drupal.org/sa-core-2018-004 and https://www.drupal.org/sa-core-2018-006. As part of fixing https://www.drupal.org/sa-core-2018-006 it was discussed whether or not this was the right way to go.

I'm not sure about moving this to here, the original idea of the request sanitizer was to obfuscate the form API fix (which we'd eventually harden against properly in the public queue).

It's a lot tidier than the code in the RedirectResponseSubscriber but not really sure about putting more functionality into the request sanitizer.

Having said all that, this is something that should be discussed in the public queue so fine with a public follow-up for it either way.

Proposed resolution

Discuss the desired architecture for the RequestSanitizer

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch, which currently accepts only minor-version allowed changes.
