There is a possible denial of service vulnerability in Action View (Rails) <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 where specially crafted accept headers can cause action view to consume 100% cpu and make the server unresponsive.

GHSA-m63j-wh5w-c252 — Denial of Service Vulnerability in Action View

Affected: RubyGems: actionview

# Denial of Service Vulnerability in Action View

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.

Releases -------- The 6.0.0.beta3, 5.2.2.1, 5.1.6.2, 5.0.7.2, and 4.2.11.1 releases are available at the normal locations.

Workarounds ----------- This vulnerability can be mitigated by wrapping `render` calls with `respond_to` blocks. For example, the following example is vulnerable:

``` ruby class UserController < ApplicationController def index render "index" end end ```

But the following code is not vulnerable:

```ruby class UserController < ApplicationController def index respond_to |format| format.html { render "index" } end end end ```

Implicit rendering is impacted, so this code is vulnerable:

```ruby class UserController < ApplicationController def index end end ```

But can be changed this this:

```ruby class UserController < ApplicationController def index respond_to |format| format.html { render "index" } end end end ```

Alternatively to specifying the format, the following monkey patch can be applied in an initializer:

``` $ cat config/initializers/formats_filter.rb # frozen_string_literal: t…
