Overview
org.webjars.npm:vite is a Native-ESM powered web dev build tool
Affected versions of this package are vulnerable to Information Exposure due to the handling of req.url which may contain unexpected characters such as #. An attacker can access and retrieve the contents of arbitrary files by sending specially crafted requests that bypass the server.fs.deny checks.
Note:
This is only exploitable if the Vite dev server is explicitly exposed to the network and running on Node or Bun runtimes, excluding Deno.
