From 6a48c759e801c5ef33a5072ef822b2b5f0c1ea86 Mon Sep 17 00:00:00 2001 From: rcourtman Date: Thu, 6 Nov 2025 23:26:03 +0000 Subject: [PATCH] Fix critical notification system bugs and security issues This commit addresses multiple critical issues identified in the notification system audit conducted with Codex: **Critical Fixes:** 1. **Queue Retry Logic (Critical #1)** - Fixed broken retry/DLQ system where send functions never returned errors - Made sendGroupedEmail(), sendGroupedWebhook(), sendGroupedApprise() return errors - Made sendWebhookRequest() return errors - ProcessQueuedNotification() now properly propagates errors to queue - Retry logic and DLQ now function correctly 2. **Attempt Counter Bug (Critical #2)** - Fixed double-increment bug in queue processing - Separated UpdateStatus() from attempt tracking - Added IncrementAttempt() method - Notifications now get correct number of retry attempts 3. **Secret Exposure (Critical #3 & #4)** - Masked webhook headers and customFields in GET /api/notifications/webhooks - Added redactSecretsFromURL() to sanitize webhook URLs in history - Truncated/redacted response bodies in webhook history - Protected against credential harvesting via API 4. **Email Rate Limiting (Critical #5)** - Added emailManager field to NotificationManager - Shared EnhancedEmailManager instance across sends - Rate limiter now accumulates across multiple emails - SMTP rate limits are now enforced correctly 5. **SSRF Protection (High #6)** - Added DNS resolution of webhook URLs - Added isPrivateIP() check using CIDR ranges - Blocks all private IP ranges (10/8, 172.16/12, 192.168/16, 127/8, 169.254/16) - Blocks IPv6 private ranges (::1, fe80::/10, fc00::/7) - Prevents DNS rebinding attacks - Returns error instead of warning for private IPs **New Features:** 6. **Health Endpoint (High #8)** - Added GET /api/notifications/health - Returns queue stats (pending, sending, sent, failed, dlq) - Shows email/webhook configuration status - Provides overall health indicator **Related to notification system audit** Files changed: - internal/notifications/notifications.go: Error returns, rate limiting, SSRF hardening - internal/notifications/queue.go: Attempt tracking fix - internal/api/notifications.go: Secret masking, health endpoint --- internal/api/notifications.go | 146 +++++++++++++++++-
