An in-range update of webpack-dev-server is breaking the build 🚨

[greenkeeper]

Version 2.4.3 of webpack-dev-server just got published.

Branch	Build failing 🚨
Dependency	webpack-dev-server
Current Version	2.4.2
Type	devDependency

This version is covered by your current version range and after updating it in your project the build failed.

As webpack-dev-server is “only” a devDependency of this project it might not break production or downstream projects, but “only” your build or test tools – preventing new deploys or publishes.

I recommend you give this issue a high priority. I’m sure you can resolve this 💪

Release Notes

v2.4.3

Security fix:

This version contains a security fix, which is also breaking change if you have an insecure configuration.
We are releasing this breaking change as patch version to protect you from attacks.
Sorry if this breaks your setup, but the fix is easy.

We added a check for the correct Host header to the webpack-dev-server.
This allowed evil websites to access your assets.

The Host header of the request have to match the listening adress or the host provided in the public option.
Make sure to provide correct values here.

The response will contain a note when using an incorrect Host header.

For usage behind a Proxy or similar setups we also added a disableHostCheck option to disable this check.
Only use it when you know what you do. Not recommended.

This version also includes this security fix for webpack-dev-middleware: https://github.com/webpack/webpack-dev-middleware/releases/tag/v1.10.2

Note: This only affect the development server and middleware. webpack and built bundles are not affected.

Bugfixes:

• Requests are not blocked when Host doesn't match listening host or public option.
• Requests to localhost or 127.0.0.1 are not blocked.

Features:

• Added disableHostCheck option to disable the host check
