This version is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of webpack-dev-server.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Do you have any ideas how I could improve these pull requests? Did I report anything you think isn’t right?
Are you unsure about how things are supposed to work?

There is a collection of frequently asked questions and while I’m just a bot, there is a group of people who are happy to teach me new things. Let them know.

Good luck with your project ✨

You rock!

GitHub Release

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.

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
