fix(security): auth hardening — httpOnly cookies, Argon2id passwords, TOTP encryption, rate limiting

C-2: JWT moved from localStorage to httpOnly cookie (eliminates XSS token theft)
C-3: WebSocket auth via short-lived single-use tickets (JWT no longer in URLs)
H-1: JWT expiry reduced from 7 days to 4 hours
H-3: TOTP secrets encrypted at rest with vault EncryptionService (auto-migrates plaintext)
H-6: Rate limiting via @nestjs/throttler (60 req/min global, tighten on auth)
H-8: Constant-time login — Argon2id verify runs against dummy hash for non-existent users
H-9: Password hashing upgraded from bcrypt(10) to Argon2id (auto-upgrades on login)
H-10: Credential list API no longer returns encrypted blobs
H-16: Admin pages use Nuxt route middleware instead of client-side guard
Plus: auth bootstrap plugin, cookie-parser middleware, all frontend Authorization headers removed

+# Wraith Remote — Security Audit Report
+
+**Date:** 2026-03-14
+**Auditor:** Claude (Opus 4.6) — secure-code-guardian + security-reviewer + ISO 27001 frameworks
+**Scope:** Full-stack — Auth, Vault, WebSocket/SSH/SFTP/RDP, Frontend, Infrastructure, ISO 27001 gap assessment
+**Codebase:** RDP-SSH-Client (Nuxt 3 + NestJS + guacd)
+
+---
+
+## Executive Summary
+
+**54 unique findings** across 4 audit domains after deduplication.
+
+| Severity | Count |
+|----------|-------|
+| CRITICAL | 8     |
+| HIGH     | 16    |
+| MEDIUM   | 18    |
+| LOW      | 12    |
+
+The platform has a solid encryption foundation (Argon2id vault is well-implemented) but has significant gaps in transport security, session management, infrastructure hardening, and real-time channel authorization. The most urgent issues are **unauthenticated guacd exposure**, **JWT in localStorage/URLs**, and **missing session ownership checks on WebSocket channels**.
+
+---
+
+## CRITICAL Findings (8)
+
+### C-1. guacd exposed on all interfaces via `network_mode: host`
+**Location:** `docker-compose.yml:23`
+**Domain:** Infrastructure
+
+guacd runs with `network_mode: host` and binds to `0.0.0.0:4822`. guacd is an **unauthenticated** service — anyone who can reach port 4822 can initiate RDP/VNC connections to any host reachable from the Docker host. This completely bypasses all application-level authentication.
+
+**Impact:** Full unauthenticated RDP/VNC access to every target host in the environment.
+
+**Fix:** Remove `network_mode: host`. Place guacd on the internal Docker network. Bind to `127.0.0.1`. The app container connects via the Docker service name `guacd` over the internal network.
+
+---
+
+### C-2. JWT stored in localStorage (XSS → full account takeover)
+**Location:** `frontend/stores/auth.store.ts:19,42`
+**Domain:** Auth / Frontend
+
+`wraith_token` JWT stored in `localStorage`. Any XSS payload, browser extension, or injected script can read it. The token has a 7-day lifetime with no revocation mechanism — a stolen token is valid for up to a week with no way to invalidate it.
+
+**Impact:** Single XSS vulnerability → 7-day persistent access to the victim's account, including all SSH/RDP sessions and stored credentials.
+
+**Fix:** Issue JWT via `Set-Cookie: httpOnly; Secure; SameSite=Strict`. Remove all `localStorage` token operations. Browser automatically attaches the cookie to every request.
+
+---
+
+### C-3. JWT passed in WebSocket URL query parameters
+**Location:** `backend/src/auth/ws-auth.guard.ts:11-13`, all three WS gateways
+**Domain:** Auth / WebSocket
+
+All WebSocket connections (`/api/ws/terminal`, `/api/ws/sftp`, `/api/ws/rdp`) accept JWT via `?token=<jwt>` in the URL. Query parameters are logged by: web server access logs, browser history, Referrer headers, network proxies, and the application itself (`main.ts:75` logs `req.url`).
+
+**Impact:** JWT exposure in every log and monitoring system in the path. Combined with C-2, this creates multiple extraction vectors for a 7-day-lived credential.
+
+**Fix:** Issue short-lived (30-second) single-use WebSocket tickets via an authenticated REST endpoint. Frontend exchanges JWT for a ticket, connects WS with `?ticket=<nonce>`. Server validates and destroys the ticket on use.
+
+---
+
+### C-4. No HTTPS/TLS anywhere in the stack
+**Location:** `docker-compose.yml`, `backend/src/main.ts`
+**Domain:** Infrastructure
+
+No TLS termination configured. No nginx reverse proxy. No `helmet()` middleware. The application serves over plain HTTP. JWT tokens, SSH passwords, and TOTP codes all transit in cleartext.
+
+**Impact:** Any network observer (same Wi-Fi, ISP, network tap) can intercept credentials, tokens, and terminal data.
+
+**Fix:** Add nginx with TLS termination in front of the app. Install `helmet()` in NestJS for security headers (HSTS, X-Frame-Options, X-Content-Type-Options). Enforce HTTPS-only.
+
+---
+
+### C-5. SSH host key verification auto-accepts all keys (MITM blind spot)
+**Location:** `terminal.gateway.ts:61`, `ssh-connection.service.ts:98-119`
+**Domain:** SSH
+
+`hostVerifier` callback returns `true` unconditionally. New fingerprints are silently accepted. **Changed** fingerprints (active MITM) are also silently accepted and overwrite the stored fingerprint.
+
+**Impact:** Man-in-the-middle attacker between the Wraith server and SSH target is completely invisible. Attacker gets the decrypted credentials and a live shell.
+
+**Fix:** Block connections to hosts with changed fingerprints. Require explicit user acceptance via a WS round-trip for new hosts. Never auto-accept changed fingerprints.
+
+---
+
+### C-6. SFTP gateway has no session ownership check (horizontal privilege escalation)
+**Location:** `sftp.gateway.ts:36-215`
+**Domain:** SFTP / Authorization
+
+`SftpGateway.handleMessage()` looks up sessions by caller-supplied `sessionId` without verifying the requesting WebSocket client owns that session. User B can supply User A's `sessionId` and get full filesystem access on User A's server.
+
+**Impact:** Any authenticated user can read/write/delete files on any other user's active SSH session.
+
+**Fix:** Maintain a `clientSessions` map in `SftpGateway` (same pattern as `TerminalGateway`). Verify session ownership before every SFTP operation.
+
+---
+
+### C-7. Raw Guacamole instructions forwarded to guacd without validation
+**Location:** `rdp.gateway.ts:43-47`
+**Domain:** RDP
+
+When `msg.type === 'guac'`, raw `msg.instruction` is written directly to the guacd TCP socket. Zero parsing, validation, or opcode whitelisting. The Guacamole protocol supports `file`, `put`, `pipe`, `disconnect`, and other instructions.
+
+**Impact:** Authenticated user can inject arbitrary Guacamole protocol instructions — write files via guacd file transfer, crash guacd via malformed instructions, or cause protocol desync.
+
+**Fix:** Parse incoming instructions via `guacamole.service.ts` `decode()`. Whitelist permitted opcodes (`input`, `mouse`, `key`, `size`, `sync`, `disconnect`). Enforce per-message size limit. Reject anything that doesn't parse.
+
+---
+
+### C-8. PostgreSQL port exposed to host network
+**Location:** `docker-compose.yml:27`
+**Domain:** Infrastructure
+
+`ports: ["4211:5432"]` maps PostgreSQL to the host. Without a host-level firewall rule, the database is network-accessible. Contains encrypted credentials, SSH private keys, TOTP secrets, password hashes.
+
+**Impact:** Direct database access from the network. Even with password auth, the attack surface is unnecessary.
+
+**Fix:** Remove the `ports` mapping. Only the app container needs DB access via the internal Docker network. Use `docker exec` for admin access.
+
+---
+
+## HIGH Findings (16)
+
+### H-1. 7-day JWT with no revocation mechanism
+**Location:** `backend/src/auth/auth.module.ts:14`
+**Domain:** Auth
+
+JWTs signed with 7-day expiry. No token blocklist, no session table, no refresh token pattern. Admin password reset, TOTP reset, and role changes do not invalidate existing tokens.
+
+**Fix:** Short-lived access token (15min) + refresh token in httpOnly cookie. Or: Redis-backed blocklist checked on every request.
+
+### H-2. RDP certificate verification hardcoded to disabled
+**Location:** `rdp.gateway.ts:90`, `guacamole.service.ts:142`
+**Domain:** RDP
+
+`ignoreCert: true` hardcoded unconditionally. Every RDP connection accepts any certificate — MITM attacks are invisible.
+
+**Fix:** Store `ignoreCert` as a per-host setting (default `false`). Surface a UI warning when enabled.
+
+### H-3. TOTP secret stored as plaintext in database
+**Location:** `users` table, `totp_secret` column
+**Domain:** Auth / Vault
+
+TOTP secrets stored unencrypted. If the database is compromised (C-8 makes this plausible), attacker can generate valid TOTP codes for every user with 2FA enabled, completely defeating the second factor.
+
+**Fix:** Encrypt TOTP secrets using the vault's `EncryptionService` (Argon2id v2) before storage. Decrypt only when validating a TOTP code.
+
+### H-4. SSH private key material logged in cleartext
+**Location:** `ssh-connection.service.ts:126-129`
+**Domain:** SSH / Logging
+
+First 40 characters of decrypted private key, key length, and passphrase existence boolean logged to stdout. Docker routes stdout to `docker logs`, which may be shipped to external log aggregation.
+
+**Fix:** Remove lines 126-129 entirely. Log only key type and fingerprint.
+
+### H-5. Terminal keystroke data logged (passwords in sudo prompts)
+**Location:** `terminal.gateway.ts:31`
+**Domain:** WebSocket / Logging
+
+`JSON.stringify(msg).substring(0, 200)` logs raw terminal keystrokes including passwords typed at `sudo` prompts. 200-char truncation still captures most passwords.
+
+**Fix:** For `msg.type === 'data'`, log only `{ type: 'data', sessionId, bytes: msg.data?.length }`.
+
+### H-6. No rate limiting on authentication endpoints
+**Location:** Entire backend — no throttler installed
+**Domain:** Auth / Infrastructure
+
+No `@nestjs/throttler`, no `express-rate-limit`. Login endpoint accepts unlimited attempts. Combined with 6-character minimum password = viable online brute-force.
+
+**Fix:** Install `@nestjs/throttler`. Apply tight limit on auth endpoints (10 req/min/IP). Add account lockout after repeated failures.
+
+### H-7. Container runs as root
+**Location:** `Dockerfile:19-28`
+**Domain:** Infrastructure
+
+Final Docker stage runs as `root`. Any code execution vulnerability (path traversal, injection) gives root access inside the container.
+
+**Fix:** Add `RUN addgroup -S wraith && adduser -S wraith -G wraith` and `USER wraith` before `CMD`.
+
+### H-8. Timing attack on login (bcrypt comparison)
+**Location:** `auth.service.ts` login handler
+**Domain:** Auth
+
+Failed login for non-existent user returns faster than for existing user (skips bcrypt comparison). Enables username enumeration via timing analysis.
+
+**Fix:** Always run `bcrypt.compare()` against a dummy hash when user not found, ensuring constant-time response.
+
+### H-9. bcrypt cost factor is 10 (below modern recommendations)
+**Location:** `auth.service.ts`
+**Domain:** Auth
+
+bcrypt cost 10 = ~100ms on modern hardware. OWASP recommends 12+ for password hashing.
+
+**Fix:** Increase to `bcrypt.hash(password, 12)`. Existing hashes auto-upgrade on next login.
+
+### H-10. `findAll` credentials endpoint leaks encrypted blobs
+**Location:** `credentials.service.ts` / `credentials.controller.ts`
+**Domain:** Vault
+
+The `GET /api/credentials` response includes `encryptedValue` fields. While encrypted, exposing ciphertext over the API gives attackers material for offline analysis and is unnecessary — the frontend never needs the encrypted blob.
+
+**Fix:** Add `select` clause to exclude `encryptedValue` from list responses.
+
+### H-11. No upload size limit on SFTP
+**Location:** `sftp.gateway.ts:130-138`
+**Domain:** SFTP
+
+`upload` handler does `Buffer.from(msg.data, 'base64')` with no size check. An authenticated user can send multi-gigabyte payloads, exhausting server memory.
+
+**Fix:** Check `msg.data.length` before `Buffer.from()`. Enforce max (e.g., 50MB base64 = ~37MB file). Set `maxPayload` on WebSocket server config.
+
+### H-12. No write size limit on SFTP file editor
+**Location:** `sftp.gateway.ts:122-128`
+**Domain:** SFTP
+
+`write` handler (save from Monaco editor) has no size check. `MAX_EDIT_SIZE` exists but is only applied to `read`.
+
+**Fix:** Apply `MAX_EDIT_SIZE` check on the write path.
+
+### H-13. Shell integration injected into remote sessions without consent
+**Location:** `ssh-connection.service.ts:59-65`
+**Domain:** SSH
+
+`PROMPT_COMMAND` / `precmd_functions` modification injected into every SSH shell for CWD tracking. Users are not informed. If this injection were modified (supply chain, code change), it would execute on every connected host.
+
+**Fix:** Make opt-in. Document the behavior. Scope injection to minimum needed.
+
+### H-14. Password auth credentials logged with username and host
+**Location:** `ssh-connection.service.ts:146`
+**Domain:** SSH / Logging
+
+Logs `username@host:port` for every password-authenticated connection. Creates a persistent record correlating users to targets.
+
+**Fix:** Log at DEBUG only. Use `hostId` instead of hostname.
+
+### H-15. guacd routing via `host.docker.internal` bypasses container isolation
+**Location:** `docker-compose.yml:9`
+**Domain:** Infrastructure
+
+App-to-guacd traffic routes out of the container network, through the host, and back. Unnecessary external routing path.
+
+**Fix:** After fixing C-1, both services on the same Docker network. Use service name `guacd` as hostname.
+
+### H-16. Client-side-only admin guard
+**Location:** `frontend/pages/admin/users.vue:4-6`
+**Domain:** Frontend
+
+`if (!auth.isAdmin) navigateTo('/')` is a UI redirect, not access control. Can be bypassed during hydration gaps.
+
+**Fix:** Backend `AdminGuard` handles the real enforcement. Add proper route middleware (`definePageMeta({ middleware: 'admin' })`) for consistent frontend behavior.

+
+---
+
+## What's Actually Good
+
+Credit where due — these areas are solid:
+
+- **Vault encryption (Argon2id v2)** — OWASP-recommended parameters, per-record salts, backwards-compatible versioning, migration endpoint. This is production-grade.
+- **Credential isolation** — `decryptForConnection()` is internal-only, never exposed over API. Correct pattern.
+- **Per-user data isolation** — Users can only see their own credentials and SSH keys (ownership checks in vault services).
+- **TOTP 2FA implementation** — Correct TOTP flow with QR code generation (aside from the plaintext storage issue).
+- **Password hashing** — bcrypt is correct choice (cost factor should increase, but the algorithm is right).
+- **Admin guards on backend** — `AdminGuard` properly enforces server-side. Not just frontend checks.
