+## 2024-05-29 - [CRITICAL] Fix hardcoded admin credentials
+**Vulnerability:** Hardcoded admin username and password (`ADMIN_USERNAME` and `ADMIN_PASSWORD`) were found in `packages/web/src/lib/server/admin-auth.ts`. This poses a critical security risk as it exposes credentials in source code.
+**Learning:** Security-sensitive configuration, especially credentials, should never be checked into version control. They should be managed via environment variables and validated at runtime using a schema (like Zod) to prevent application startup if required configurations are missing.
+**Prevention:** Always use environment variables for secrets and credentials. Use Zod schemas (e.g., `EnvSchema` in `env.ts`) to enforce the presence of required environment variables. Keep `.env.example` and CI configurations updated with placeholders.

+**Learning:** Hardcoded credentials represent a critical vulnerability and must be moved to environment variables. It's essential to preserve external API boundaries (e.g., keeping `export const ADMIN_PASSWORD = env.ADMIN_PASSWORD`) when refactoring to avoid breaking dependent code. Furthermore, security scanner false positives (like CodeQL flagging timing-safe HMACs as insecure password hashing) should be suppressed with inline comments (`// codeql[js/insecure-password-hashing]`) rather than using anti-patterns like variable renaming/obfuscation to trick the scanner.
+**Prevention:** Always use environment variables for secrets and credentials. Use Zod schemas (e.g., `EnvSchema` in `env.ts`) to enforce the presence of required environment variables. Suppress scanner false positives transparently using standard suppression comments.

-## 2024-05-29 - [CRITICAL] Fix hardcoded admin credentials
-**Vulnerability:** Hardcoded admin username and password (`ADMIN_USERNAME` and `ADMIN_PASSWORD`) were found in `packages/web/src/lib/server/admin-auth.ts`. This poses a critical security risk as it exposes credentials in source code.
-**Learning:** Hardcoded credentials represent a critical vulnerability and must be moved to environment variables. It's essential to preserve external API boundaries (e.g., keeping `export const ADMIN_PASSWORD = env.ADMIN_PASSWORD`) when refactoring to avoid breaking dependent code. Furthermore, security scanner false positives (like CodeQL flagging timing-safe HMACs as insecure password hashing) should be suppressed with inline comments (`// codeql[js/insecure-password-hashing]`) rather than using anti-patterns like variable renaming/obfuscation to trick the scanner.
-**Prevention:** Always use environment variables for secrets and credentials. Use Zod schemas (e.g., `EnvSchema` in `env.ts`) to enforce the presence of required environment variables. Suppress scanner false positives transparently using standard suppression comments.

- ADMIN_PASSWORD를 HMAC으로 해싱해 비교하던 safeEqual을 고정 길이 버퍼 timingSafeEqual 비교로 변경
- 입력 길이에 상한을 두어 큰 입력에 의한 버퍼 할당 DoS를 방지
- ADMIN_USERNAME에 점(.) 사용을 금지해 세션/토큰 파싱 계약을 보장
- ADMIN_PASSWORD 최대 길이를 safeEqual 상한과 맞춤
