2026-02-07 - Telegram Bot Authorization Bypass
Vulnerability: The Telegram Deployment Bot (scripts/telegram_deploy_bot.py) contained a "Fail Open" vulnerability where omitting the TELEGRAM_ALLOWED_USER_IDS environment variable resulted in granting access to all Telegram users instead of none.
Learning: Security controls must default to deny (Fail Closed). Implicitly allowing access when configuration is missing creates silent vulnerabilities that are hard to detect until exploited.
Prevention: Ensure all authorization checks explicitly return False or throw an exception if the access control list is empty or undefined. Never default to True in security-critical paths.
2026-02-11 - Web Dashboard Error Leakage
Vulnerability: The web dashboard (scripts/web_dashboard.py) returned raw exception messages to the client on error, potentially exposing sensitive system paths or configuration details.
Learning: Detailed error messages intended for developers can become information disclosure vectors when exposed to end-users.
Prevention: Implement generic error responses (e.g., "Internal Server Error") for client-facing endpoints while logging detailed stack traces securely on the server side.
