📝 WalkthroughWalkthrough웹훅 URL 검증 헬퍼가 추가되었습니다. 내부, 루프백, 사설 IPv4 주소를 차단합니다. 웹훅 생성 테스트는 외부 도메인을 사용하도록 변경되었습니다. Changes웹훅 SSRF 방어
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change improves webhook URL filtering, but crafted DNS, IPv6, or redirect targets can still reach internal services, and HTTP webhooks can expose signed payloads. These security gaps should be addressed before merge. Sequence Diagram(s)sequenceDiagram

Primary authority: IANA IPv6 Special-Purpose Address Space registry; RFC 6052; RFC 8215. This is interoperability correctness as well as SSRF hardening: rejecting a globally reachable WKP unconditionally is over-restrictive, while admitting the local-use /48 is wrong. |
