chore: Bump webpack-dev-server from 5.2.2 to 5.2.6

[dependabot]

Bumps webpack-dev-server from 5.2.2 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)
• compatibility with event target and universal target and lazy compilation (574026c)
• overlay: add ESC key to dismiss overlay (#5598) (f91baa8)
• progress indicator styles (#5557) (41a53a1)
• upgrade selfsigned to v5
