CVE-2025-31125Known exploitationPublic exploitNetwork attack vector

Arbitrary file read via transform query bypass

Published Mar 31, 2025 · Updated Jan 23, 2026

Improper access control in affected Vite development servers allows remote attackers to read arbitrary files through crafted query strings. The transform middleware applied serving-access checks to raw and URL requests but omitted inline queries and failed to recognize raw followed by import. Exploitation requires an app exposed with --host or server.host and user interaction that triggers the request; the consequence is read-only file disclosure.
