From 4c75bf571399a0317a18bc62dbe0db019d4eb15d Mon Sep 17 00:00:00 2001 From: ggq-admin Date: Mon, 27 Oct 2025 00:50:18 +0100 Subject: [PATCH] security: Implement critical safeguards before public release - Add .gitignore to prevent secret leakage - Implement YOLO guard with double-confirmation flow * Environment variable gate (YOLO_MODE=1) * Typed confirmation phrase + one-time code * Time-limited approval tokens (5 min TTL) * Single-use tokens with audit logging - Add rate limiting (10/min, 100/hour, 500/day) * Token bucket implementation * Per-session tracking * Automatic bucket reset - Integrate safeguards into existing code * Rate limiter in SecureBridge.send_message() * YOLO guard in YOLOMode.execute_command() * Dry-run mode by default - Add security test suite * .gitignore validation * YOLO guard functional tests * Rate limiter verification * Integration checks All security measures tested and verified.
