Implement three-layer SSRF protection: - Layer 1: URL pre-validation (existing) - Layer 2: network.NewSafeHTTPClient() with connection-time IP validation - Layer 3: Redirect target validation New package: internal/network/safeclient.go - IsPrivateIP(): Blocks RFC 1918, loopback, link-local (169.254.x.x), reserved ranges, IPv6 private - safeDialer(): DNS resolve → validate all IPs → dial validated IP (prevents DNS rebinding/TOCTOU) - NewSafeHTTPClient(): Functional options (WithTimeout, WithAllowLocalhost, WithAllowedDomains, WithMaxRedirects) Updated services: - notification_service.go - security_notification_service.go - update_service.go - crowdsec/registration.go (WithAllowLocalhost for LAPI) - crowdsec/hub_sync.go (WithAllowedDomains for CrowdSec domains) Consolidated duplicate isPrivateIP implementations to use network package. Test coverage: 90.9% for network package CodeQL: 0 SSRF findings (CWE-918 mitigated) Closes #450
docs/issues - Issue Specification Files
This directory contains markdown files that are automatically converted to GitHub Issues when merged to main or development.
How It Works
- Create a markdown file in this directory using the template format
- Add YAML frontmatter with issue metadata (title, labels, priority, etc.)
- Merge to main/development - the
docs-to-issues.ymlworkflow runs - GitHub Issue is created with your specified metadata
- File is moved to
docs/issues/created/to prevent duplicates
Quick Start
Copy _TEMPLATE.md and fill in your issue details:
---
title: "My New Issue"
labels:
- feature
- backend
priority: medium
---

Sub-Issues
To create multiple related issues from one file, set create_sub_issues: true:
---
title: "Main Testing Issue"
labels: [testing]
create_sub_issues: true
---
# Main Testing Issue
Overview content for the parent issue.
## Unit Testing
This section becomes a separate issue.
## Integration Testing
This section becomes another separate issue.
Manual Trigger
You can manually run the workflow with:
# Dry run (no issues created)
gh workflow run docs-to-issues.yml -f dry_run=true
# Process specific file
gh workflow run docs-to-issues.yml -f file_path=docs/issues/my-issue.md
Labels
Labels are automatically created if they don't exist. Common labels:
- Priority:
critical,high,medium,low - Type:
feature,bug,enhancement,testing,documentation - Component:
