| Описание | Silicon is a Flask-based personal knowledge base with 262 GitHub stars. The entire application has zero authentication - no login page, no session check, no password protection, no middleware. All write endpoints are publicly accessible without any form of authentication. An unauthenticated attacker can create, edit, or modify any page in the knowledge base via POST requests to /edit/<title>. Other write endpoints like /toc (POST) and /related/<title> (POST/DELETE) are equally unprotected. The code in views.py has no @login_required decorators, no session checks, and no auth middleware. The create_app() factory in __init__.py does not register any authentication mechanism. This allows complete defacement or data manipulation of any silicon instance exposed to the network.
