This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to v5, this PR will be updated.

webpack-dev-server@5.2.6
Patch Changes
fix: allow undefined as the Server constructor options argument again (by @bjohansebas in #5695)
Restores accepting undefined (defaulting it to {}) for the options
argument, so passing a webpack config's optional devServer field type-checks and works as before.
Protect the built-in state-changing routes (/webpack-dev-server/invalidate and /webpack-dev-server/open-editor) against cross-site request forgery. Requests are now checked with Sec-Fetch-Site (falling back to an Origin/Host comparison when it is absent), so a cross-site page can no longer trigger a rebuild or open a file in the editor. Same-origin requests, user-initiated navigations, and non-browser clients (e.g. curl) are unaffected. (by @bjohansebas in #5698)
Handle malformed Host and Origin header values gracefully when validating requests. (by @bjohansebas in #5699)
