Vite allowed any websites to send any requests to the development server and read the response due to default CORS settings and lack of validation on the Origin header for WebSocket connections. [!WARNING] This vulnerability even applies to users that only run the Vite dev server on the local machine and does not expose the dev server to the network.
The contents of arbitrary files can be returned to the browser.
We discovered a DOM Clobbering vulnerability in Vite when building scripts to cjs/iife/umd output format. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. Note that, we have identified similar security issues in Webpack: https://github.com/webpack/webpack/security/advisories/GHSA-4vvj-4cpr-p986
Vite dev server option server.fs.deny did not deny requests for patterns with directories. An example of such a pattern is /foo/**/*.
Vite is a frontend tooling framework for javascript. The Vite dev server option server.fs.deny can be bypassed on case-insensitive file systems using case-augmented versions of filenames. Notably this affects servers hosted on Windows. This bypass is similar to CVE-2023-34092 – with surface area reduced to hosts having case-insensitive filesystems. Since picomatch defaults to case-sensitive glob matching, but the file server does not discriminate; a block list bypass is possible. By …
Vite is a website frontend framework. When Vite's HTML transformation is invoked manually via server.transformIndexHtml, the original request URL is passed in unmodified, and the html being transformed contains inline module scripts (<script type="module">…</script>), it is possible to inject arbitrary HTML into the transformed output by supplying a malicious URL query string to server.transformIndexHtml. Only apps using appType: 'custom' and using the default Vite HTML middleware are affected. The HTML …
Vite provides frontend tooling. Prior to versions 2.9.16, 3.2.7, 4.0.5, 4.1.5, 4.2.3, and 4.3.9, Vite Server Options (server.fs.deny) can be bypassed using double forward-slash (//) allows any unauthenticated user to read file from the Vite root-path of the application including the default fs.deny settings (['.env', '.env.', '.{crt,pem}']). Only users explicitly exposing the Vite dev server to the network (using –host or server.host config option) are affected, and only files in …
Vite before v2.9.13 was discovered to allow attackers to perform a directory traversal via a crafted URL to the victim's service.
