vitest.dev Announcing Vitest 4.0 Vitest 4.0 Release Announcement

Vitest @vitest_dev Jun 1

We've published a Browser Mode security advisory.

CDP-capable providers like Playwright Chromium with the browser API exposed to the network allowed attackers to run code on the host.

Update vitest/browser to 5.0.0-beta.4, 4.1.8, or 3.2.6.
Vite+ users: Upgrade to 0.1.24

Vitest @vitest_dev May 19

🚨 We are publishing Vitest 4.1.6 and Vitest 5.0.0-beta.3 to resolve recent vulnerabilities:

- `--api` and `--ui` exposed arbitrary files to the network
- `--api` allowed arbitrary execution
- `?otelCarrier` XSS

In the next version of Claude Code..

We're introducing two new Skills: /simplify and /batch. I have been using both daily, and am excited to share them with everyone.

Combined, these kills automate much of the work it used to take to (1) shepherd a pull request to production and (2) perform straightforward, parallelizable code migrations.
