No fix available

Details

@vitejs/plugin-rs provides React Server Components (RSC) support for Vite. Prior to version 0.5.8, the /__vite_rsc_findSourceMapURL endpoint in @vitejs/plugin-rsc allows unauthenticated arbitrary file read during development mode. An attacker can read any file accessible to the Node.js process by sending a crafted HTTP request with a file:// URL in the filename query parameter. Version 0.5.8 fixes the issue.
