CVE-2025-32395 is an arbitrary file read vulnerability in the Vite development server affecting versions prior to 6.2.6, 6.1.5, 6.0.15, 5.4.18, and 4.5.13. When Vite is run on Node or Bun, malformed HTTP requests containing a '#' character in the request-target may be passed to userland instead of being rejected. Vite assumed req.url would not contain '#', and this assumption caused its server.fs.deny protection to be bypassed. An attacker can leverage this behavior, including with the @fs path handling and a URL-encoded hash character (%23), to cause the dev server to return the contents of arbitrary files to the browser. The issue does not affect Deno in the described scenario.
