Upgrade to Doorkeeper v4.2.6 or later


Apologies. This fails to account for a non-trivial scenario.

Any software using Doorkeeper that has generated its own custom views[0]
requires manual work to verify there's no explicit HTML in the
`client_name` and `native_redirect_uri` field values.

This has been updated in the bulletin's Fix section[1].
