opencode-ai is vulnerable to Missing Authentication

High Risk
This Affects:
opencode-aiTL;DR
OpenCode's HTTP server starts automatically without authentication middleware and with permissive CORS (Access-Control-Allow-Origin: *). Any local process—or a malicious website via cross-origin requests—can call endpoints such as POST /session/:id/shell, POST /pty, and GET /file/content to run arbitrary shell commands and read files under the user's privileges. The fix authenticates the HTTP server before accepting those requests.
