build(deps): bump webpack-dev-server and @wordpress/scripts

[dependabot]

Bumps webpack-dev-server to 5.2.6 and updates ancestor dependency @wordpress/scripts. These dependencies need to be updated together.

Updates webpack-dev-server from 4.15.2 to 5.2.6

Release notes

Sourced from webpack-dev-server's releases.

v5.2.6

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)

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)

v5.2.4

5.2.4 (2026-05-11)

Bug Fixes

• set Cross-Origin-Resource-Policy header to prevent source code theft over HTTP

v5.2.3

5.2.3 (2026-01-12)

Bug Fixes

• add cause for errorObject (#5518) (37b033d)

• overlay: add ESC key to dismiss overlay (#5598) (f91baa8)
• progress indicator styles (#5557) (41a53a1)
• upgrade selfsigned to v5

v5.2.2

5.2.2 (2025-06-03)

Bug Fixes

• "Overlay enabled" false positive (18e72ee)
• do not crush when error is null for runtime errors (#5447) (309991f)
• remove unnecessary header X_TEST (#5451) (64a6124)

Updates @wordpress/scripts from 30.22.0 to 34.1.0

Changelog

Sourced from @​wordpress/scripts's changelog.

34.1.0 (2026-08-12)

Bug Fixes

• Set Sass's charset option to false so production builds no longer emit a UTF-8 BOM in the middle of the extracted CSS (#81383).

34.0.0 (2026-07-29)

Breaking Changes

• Upgrade the bundled Jest packages from v29 to v30 (#80767).

Enhancements

• `format`: Detect `prettier.config.mjs` so the bundled default config is not used when one is present ([#80422](https://github.com/WordPress/gutenberg/pull/80422)).
  

33.0.0 (2026-07-14)

Breaking Changes

• The test-e2e command now runs the Playwright-based end-to-end test runner instead of Puppeteer (test-playwright remains available as an alias). Removed the Puppeteer test environment and configuration (jest-environment-puppeteer, jest-e2e.config.js, puppeteer.config.js) along with the puppeteer-core and expect-puppeteer dependencies. Puppeteer-specific options (e.g. --puppeteer-interactive, --puppeteer-devtools) are no longer supported (#60357).

Enhancements

• Widen React peer dependency ranges to ^18 || ^19 to support both React 18 and React 19 environments (#80024).
• Update stylelint to ^16.26.1 (#79648).
• Widen the @playwright/test peer dependency to >=1 and mark it optional, so consumers aren't forced to bump Playwright or satisfy it under strict peer deps (#78632).
• Update webpack-dev-server to ^5.2.1, resolving several Dependabot security alerts and migrating the internal dev-server proxy config to the v5 array format (#80347).

32.6.0 (2026-07-01)

32.5.0 (2026-06-24)

Enhancements

• lint-style: Detect .cjs and .mjs config files so the bundled default config is not used when one of these is present (#79226).

32.4.1 (2026-06-16)

32.4.0 (2026-06-10)

32.3.0 (2026-05-27)

32.2.0 (2026-05-14)

32.1.0 (2026-04-29)
