Release Notes

webpack/webpack-dev-server (webpack-dev-server)

v5.2.6

Compare Source

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)

v5.2.5

Patch Changes

• Skip the HMR WebSocket path when forwarding upgrade requests to user-defined proxies, so custom proxy WebSocket upgrades are no longer intercepted by the dev server. (by @​bjohansebas in #​5680)

[openshift-ci]

Hi @red-hat-konflux-kflux-prd-rh02[bot]. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
