Node 20 reached end-of-life on 2026-04-30, Node 21 in June 2024 and Node 23 in June 2025. Keep the supported LTS lines (22 and 24). This also unblocks the Vitest 4 security upgrade: Vite 8 (installed by Vitest 4) crashes on Node 21, and Vitest 5 requires Node ^22.12. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Resolves the @vitest/mocker path traversal / arbitrary file read advisory
(affects >=2.1.0 <4.1.11).
- Replace the react-native-testing-mocks/vitest plugin with an inline
config and a local test environment: the plugin's CJS environment is not
unwrapped by Vitest 4 ("environment.setup is not a function") and relies
on the removed `transformMode` option.
- Move `poolOptions.forks.execArgv` to `test.execArgv` (`poolOptions` was
removed in Vitest 4).

Upgrading Vitest to 4.1.11: full summary
The problem
GitHub flagged a vulnerability in @vitest/mocker, a package that Vitest installs:
Advisory: "Vitest: Path Traversal / Arbitrary File Read via @vitest/mocker Redirect Mock"
Affected versions: >=2.1.0 <4.1.11
The repo had: vitest@3.2.7, which installs @vitest/mocker@3.2.7. That version is vulnerable.
No 3.x release fixes it, so the only fix is upgrading to Vitest 4.1.11, a new major version.
Vitest is only a dev dependency of package/, used to run the tests. It isn't part of the published library, so people who install react-native-spotlight-tour were never affected. The alert concerns the development environment and CI.
