Executive Summary -A CodeQL security scan has flagged line 176 in `url_testing.go` with: **"The URL of this request depends on a user-provided value."** While this is a **false positive** (comprehensive SSRF protection exists via PR #450), this document provides defense-in-depth enhancements. +Wildcard SSL certificates (e.g., `*.example.com`) are essential for modern multi-tenant and subdomain-heavy deployments, but Let's Encrypt and other ACME providers **require DNS-01 challenges** to issue them. Currently, Charon only supports HTTP-01 challenges, which cannot validate wildcard domains. This limitation blocks users who need flexible subdomain management from using automatic certificate issuance. -**Current Status**: ✅ **PRODUCTION READY** -- 4-layer defense architecture -- 90.2% test coverage -- Zero vulnerabilities -- CodeQL suppression present +This feature is critical for the beta release because wildcard certificate support is a fundamental expectation of any production-grade reverse proxy manager. Without it, users must manually provision and upload certificates, defeating the purpose of automated TLS management that Charon promises. -**Enhancement Goal**: Add 5 additional security layers for belt-and-suspenders protection. +The implementation involves creating a secure credential storage system with AES-256-GCM encryption, a new `DNSProvider` entity with full CRUD operations, extending the Caddy configuration generator to emit DNS challenge blocks, and building a complete frontend management interface. The approach prioritizes security (encrypted credentials at rest), extensibility (supporting 10+ major DNS providers), and user experience (test-before-save, clear status indicators). --- -## 1.
