Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in the Rack middleware package of RubyGems, where response bodies will not close under certain circumstances. This flaw allows an attacker to iterate requests to force ActionDispatch::Executor to not close, allowing subsequent requests to leak data from ActiveSupport::CurrentAttributes.

Description Marian Rehak 2022-03-11 11:34:06 UTC 
In the event a response is *not* notified of a `close`, `ActionDispatch::Executor` will not know to reset thread local state for the next request. This can lead to data being leaked to subsequent requests.
