> **Denial of Service Vulnerability in Action View**
> There is a potential denial of service vulnerability in actionview.
> This vulnerability has been assigned the CVE identifier CVE-2019-5419.
>
> Impact
> ------
> Specially crafted accept headers can cause the Action View template location
> code to consume 100% CPU, causing the server unable to process requests. This
> impacts all Rails applications that render views.
>
> All users running an affected release should either upgrade or use one of the
> workarounds immediately.
>
> Workarounds
> -----------
> This vulnerability can be mitigated by wrapping `render` calls with
> `respond_to` blocks. For example, the following example is vulnerable:
>
> ```
> class UserController < ApplicationController
> def index
> ... (truncated)

> Patched versions: >= 6.0.0.beta3; \~> 5.2.2, >= 5.2.2.1; \~> 5.1.6, >= 5.1.6.2; \~> 5.0.7, >= 5.0.7.2; \~> 4.2.11, >= 4.2.11.1

> # File Content Disclosure in Action View
>
> Impact
> ------
> There is a possible file content disclosure vulnerability in Action View.
> Specially crafted accept headers in combination with calls to `render file:`
> can cause arbitrary files on the target server to be rendered, disclosing the
> file contents.
>
> The impact is limited to calls to `render` which render file contents without
> a specified accept format. Impacted code in a controller looks something like
> this:
>
> ```
> class UserController < ApplicationController
> def index
> render file: "#{Rails.root}/some/file"
> end
> end
