id: CVE-2025-31125

info:
  name: Vite Development Server - Path Traversal
  author: martian,ritikchaddha,v2htw
  severity: medium
  description: |
    Path traversal vulnerability in Vite development server's @fs endpoint allows attackers to access files outside the intended directory. When exposed to the network, attackers can exploit this via crafted URLs to access sensitive system files.
  impact: |
    Attackers can exploit path traversal in the @fs endpoint to access files outside the intended directory when the Vite dev server is exposed to the network, potentially reading sensitive system files.
  remediation: |
    Upgrade to the patched version or avoid exposing the Vite development server to the network (do not use --host flag or configure server.host); if upgrading is not immediately possible, implement access restrictions to the Vite development server
