A critical vulnerability in code-server's `/mint-key` endpoint allowed unauthenticated cross-origin requests to generate or retrieve VS Code web server authentication keys. By adding the `ensureAuthenticated` middleware to the POST handler, the fix ensures only authenticated users can mint new keys, eliminating the CSRF attack vector.
A critical vulnerability in a Node.js Panel Connector API (CVE-2025-7783) left 14 endpoints—including shell command execution, file deletion, and file writing—completely open to unauthenticated access. The comment in the source code even declared "NO AUTH — Full Open Access," making it a textbook example of a missing authentication control. The fix adds a Bearer token middleware guard on all `/api` routes, blocking unauthorized requests before they reach any sensitive handler.
