Detailsinfo

A vulnerability, which was classified as critical, was found in vitest-dev Vitest up to 3.2.4/4.1.7/5.0.0-beta.3. Affected is the function cdp of the file vite.config.ts of the component Browser Mode. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Vitest is a testing framework powered by Vite. From 3.0.0 until 3.2.5, 4.1.8, and 5.0.0-beta.4, Vitest Browser Mode exposed a cdp() API that forwarded raw Chrome DevTools Protocol methods without being gated by allowWrite or allowExec, allowing a remote client with exposed browser API metadata to use CDP Page.setDownloadBehavior and Runtime.evaluate to overwrite vite.config.ts and execute attacker-controlled Node.js code. This issue is fixed in versions 3.2.5, 4.1.8, and 5.0.0-beta.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-53633 since 06/09/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
