Charles Bochet 9100fb1e9f security: scoped resolution for webpack-dev-server 5.2.4 (Dependabot alerts 1237/691/692) (#21420)
Closes 3 webpack-dev-server Dependabot alerts —
[1237](https://github.com/twentyhq/twenty/security/dependabot/1237),
[691](https://github.com/twentyhq/twenty/security/dependabot/691),
[692](https://github.com/twentyhq/twenty/security/dependabot/692) — with
a **scoped** resolution:
`@electron-forge/plugin-webpack/webpack-dev-server: 5.2.4`.

(These numbers are Dependabot **alert** IDs, not issue/PR numbers —
written without `#` to avoid cross-linking unrelated issues, per review
feedback.)

### Why a resolution (the one place it's unavoidable)
webpack-dev-server is pulled **only** by
`@electron-forge/plugin-webpack` (twenty-companion's build tooling), and
**no electron-forge release uses webpack-dev-server 5** — not even
`8.0.0-alpha.9` still pins `^4`. There is no parent-upgrade path, so a
resolution is the only mechanism.

### Scoped, not global
Per review feedback, the resolution targets
`@electron-forge/plugin-webpack/webpack-dev-server` rather than a global
override — it only forces v5 under electron-forge (the sole consumer),
limiting blast radius. Verified the scoped syntax is honored: removing
it reverts the lockfile to `webpack-dev-server@npm:^4.0.0`; with it, the
lock pins `webpack-dev-server@npm:5.2.4` and `yarn install --immutable`
passes.

### Why it's safe (constructor did NOT change v4→v5)
`@electron-forge/plugin-webpack@7` calls `new
WebpackDevServer(this.devServerOptions(), compiler)`.
webpack-dev-server's constructor is `constructor(options, compiler)` in
**both v4 and v5** (verified in `lib/Server.js:331` and
`types/lib/Server.d.ts:1179`). The `(compiler, options)` → `(options,
compiler)` swap happened at **v3 → v4**, not v4 → v5. The plugin passes
only options unchanged in v5 (`hot`, `devMiddleware.writeToDisk`,
`historyApiFallback`, `port`, `setupExitSignals`, `static`, `headers`)
and uses none of the hooks v5 removed.

### Scope / verification
- `yarn install --immutable` ✓; webpack-dev-server resolves to 5.2.4
only (was 4.15.2), no vulnerable copy remains.
- Only exercised by `electron-forge start` (dev HMR); production
`make`/`package` builds don't use it, and **twenty-companion has no CI
workflow**, so this can't affect CI.
- Residual manual check (not CI-covered): `yarn start:electron` in
twenty-companion still boots the dev server.

Installation

Cloud

The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.

Build an app

Scaffold a new app with the Twenty CLI:

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty app:publish --private

See the app development guide for objects, views, agents, and logic functions.
