High [CVE-2026-47428] Arbitrary code execution via crafted browser-runner URL
CVE-2026-47428Source published Source updated
Vitest is a testing framework powered by Vite. From 4.0.17 until 4.1.6 and 5.0.0-beta.3, Vitest Browser Mode served /__vitest_test__/ with the otelCarrier query parameter inserted directly into an inline module script, allowing a crafted browser-runner URL to execute arbitrary JavaScript in the Vitest server origin and recover VITEST_API_TOKEN for authenticated API calls. In Vitest Browser Mode, a remote attacker could craft a specific browser-runner URL that, when visited, would allow the execution of arbitrary JavaScript code within the Vitest server.

- Mitigation guidance
- No mitigation is required for Red Hat shipping products, as the vulnerable @vitest/browser package and Browser Mode feature are not present or enabled in any Red Hat product. Development teams using Vitest as a build/test-time dependency should avoid introducing @vitest/browser or enabling Browser Mode in CI/local environments, and should upgrade to Vitest >=4.1.6 (or >=5.0.0-beta.3 on the 5.x beta line) where Vitest is used, as a matter of general hygiene.
