Exposure of Sensitive Information to an Unauthorized Actor in org.webjars.npm:vite

CVE-2025-31486

  • org.webjars.npm:vite
  • vite
Medium
5.3/10

Summary

A vulnerability in Vite allows the contents of arbitrary files to be returned to the browser. By appending "?.svg" along with "?.wasm?init" or setting the "sec-fetch-dest: script" header, an attacker can bypass the "server.fs.deny" restriction. This is only possible if the file is smaller than the default "build.assetsInlineLimit" (4kB) and when the Vite development server is explicitly exposed to the network via the "--host" flag or "server.host" configuration. The vulnerability affects vite package versions through 4.5.11, 5.0.0-beta.0 through 5.4.16, 6.0.0-alpha.0 through 6.0.13, 6.1.0-beta.0 through 6.1.3, and 6.2.0-beta.0 through 6.2.4.
