**Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
**Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
**Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
## 2024-07-12 - Prevent User Enumeration via Authentication Timing Attacks
**Vulnerability:** The login endpoint verified the provided password hash only if a user record was found. If no user was found, it returned early. This meant requests for valid emails took longer to process than invalid emails, enabling attackers to enumerate valid email addresses via timing discrepancies.
**Learning:** Returning early on failed database lookups before performing expensive cryptographic operations creates a measurable timing difference. Cryptographic paths must be balanced.
**Prevention:** Always evaluate passwords against a `DUMMY_HASH` if the user lookup fails, ensuring constant-time execution regardless of whether the user exists. Explicitly coerce passwords to strings (`typeof password === 'string' ? password : ''`) before passing them to the hash verifier to avoid TypeErrors from unexpected JSON payloads while still evaluating against the dummy hash.

실제 인증 엔드포인트를 호출하도록 테스트를 변경하세요.

simulateLoginserver/app.mjs의 구현을 호출하지 않고 동일한 DUMMY_HASHverifyPassword 로직을 다시 구현합니다. 따라서 production 인증 코드가 회귀해도 이 테스트는 계속 통과할 수 있습니다. 또한 비밀번호 변경과 계정 삭제 경로는 검증하지 않습니다. 실제 Hono 라우트를 호출하거나 production verifier 호출을 관찰하는 방식으로 세 경로를 테스트하세요.

In `@tests/unit/auth-timing.test.mjs` around lines 6 - 12, Replace the local
simulateLogin implementation with tests that invoke the actual authentication
routes from server/app.mjs, covering login, password change, and account
deletion. Reuse the production Hono route handling and assert each path’s
authentication behavior so regressions in the real verifier and DUMMY_HASH flow
are detected.
