Threats tagged 'brew-vite-cve-2026-112947'

CVE-2026-112947 is a path traversal vulnerability in the Vite development server that allows an attacker to retrieve the first 4 bytes of arbitrary files on disk by sending a request with the query parameter '?vite-wasm-instance'. This occurs because the internal Wasm plugin's load hook reads files without applying server.fs access restrictions. The vulnerability affects Vite versions >=0.2.8 <1.1.0, >=8.2.0 <8.2.4, and >=8.3.0 <8.3.3. It only impacts applications that expose the Vite dev server to the network, run on Node.js or Deno, and have sensitive information in the first 4 bytes of a file. The issue is fixed in versions 1.1.0, 8.2.4, and 8.3.3.
