## Summary 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. **Severity:** High **Attack Vector:** Network **Privileges Required:** None **Scope:** Development mode only (`vite dev`) --- ## Impact ### Who Is Affected? - **All developers** using `@vitejs/plugin-rsc` during development - Projects running `vite dev` with the RSC plugin enabled ### Attack Scenarios 1. **Network-Exposed Dev Servers:** When developers run `vite --host 0.0.0.0` (common for mobile testing), attackers on the same network can read files. 2. ~**XSS-Based Attacks:**~ ~If the application has an XSS vulnerability, malicious JavaScript can fetch sensitive files and exfiltrate them.~ 3. ~**Malicious Dependencies:** ~ ~A compromised npm package could incl...
