Detailsinfo

A vulnerability, which was classified as critical, has been found in vitest-dev vitest up to 0.0.125/1.6.0/2.1.8/3.0.4. This issue affects some unknown processing of the component API Server. The manipulation with an unknown input leads to a missing origin validation in websockets vulnerability. Using CWE to declare the problem leads to CWE-1385. The product uses a WebSocket, but it does not properly verify that the source of data or communication is valid. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Vitest is a testing framework powered by Vite. Affected versions are subject to arbitrary remote Code Execution when accessing a malicious website while Vitest API server is listening by Cross-site WebSocket hijacking (CSWSH) attacks. When `api` option is enabled (Vitest UI enables it), Vitest starts a WebSocket server. This WebSocket server did not check Origin header and did not have any authorization mechanism and was vulnerable to CSWSH attacks. This WebSocket server has `saveTestFile` API that can edit a test file and `rerun` API that can rerun the tests. An attacker can execute arbitrary code by injecting a code in a test file by the `saveTestFile` API and then running that file by calling the `rerun` API. This vulnerability can result in remote code execution for users that are using Vitest serve API. This issue has been patched in versions 1.6.1, 2.1.9 and 3.0.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2025-24964 since 01/29/2025. The exploitation is known to be easy.
