ronitchidara 874caa32bc security: add gateway rate limiting and security warnings
- Implement token bucket rate limiter with per-client tracking
- Add configurable limits: unauthenticated (60/min), authenticated (unlimited)
- Add channel message rate limiting (200/min per channel)
- Implement exponential backoff after auth failures (1s base, 60s max)
- Add startup security warnings for non-loopback binding without auth
- Add GatewayRateLimitConfig type to config schema
- All settings configurable via gateway.rateLimit in clawdbot.json

Clawdbot Security Hardening Plan - Phase 1

Location: This file lives in the security worktree at ~/clawdbot-security Branch: phase1-security Purpose: Tracks progress on Phase 1 Security Hardening tasks. Other Claude Code sessions can pick up incomplete tasks.


Worktree Setup

Git worktrees are set up for parallel development:

~/clawdbot-analysis/        # main branch (original clone)
~/clawdbot-security/        # phase1-security branch (THIS WORKTREE)

To create additional worktrees for other phases:

cd ~/clawdbot-analysis
git worktree add ../clawdbot-architecture -b phase2-architecture
git worktree add ../clawdbot-ux -b phase3-ux

Phase 1 Task Status

    • High: sudo, passwd, visudo, iptables, user management (BLOCKED, requires explicit approval)

    • src/telegram/token.test.ts - Updated tests with skipSecrets option
    • src/telegram/accounts.ts - Updated type to include "secrets" source
    • src/slack/accounts.ts - Added secrets as Priority 1 source with skipSecrets option
    • src/web/auth-store.ts - Added encrypted credentials support for WhatsApp
  • Features:
    • macOS Keychain via security command
    • Linux Secret Service via secret-tool (libsecret)
    • Fallback to AES-256-GCM encrypted files with PBKDF2 key derivation
    • Machine-derived encryption key for file fallback
    • Utilities: generateSecureToken, hashSecret, verifySecretHash
    • File encryption utilities: encryptFile, decryptFile, readPossiblyEncryptedFile
    • WhatsApp creds.json now supports .enc encrypted format
    • Migration helper: migrateWebCredsToEncrypted() for WhatsApp
    • All token resolution functions now check secrets-manager first
  • Commits:
    • a6f48ac29 "security: add cross-platform secrets manager"
    • TBD "security: integrate secrets-manager with all token stores"
  • TODO:
    • Add migration CLI command: clawdbot secrets migrate
    • Update clawdbot doctor to check for unencrypted credentials

1.4 Gateway Authentication & Rate Limiting

  • Files Created/Modified:
    • src/gateway/rate-limit.ts - New rate limiting module (~370 lines)
    • src/gateway/rate-limit.test.ts - 19 tests
    • src/gateway/server-startup-log.ts - Added security warnings

PENDING

1.5 Pairing & Approval Hardening

Objective: Increase entropy and add replay protection.

Files to Modify:

  • src/pairing/pairing-store.ts
    • Increase pairing code from 8 chars (~40 bits) to 16 chars (~80 bits)
    • Add rate limiting on pairing attempts (1/sec max)
    • Sign pairing store with HMAC
  • src/infra/exec-approvals.ts
    • Implement one-time-use nonces for approval tokens
    • Add nonce tracking to prevent replay attacks

Current Pairing Code:

  • 8 chars, alphabet: ABCDEFGHJKLMNPQRSTUVWXYZ23456789 (32 chars = 5 bits each)
  • Total entropy: ~40 bits (too low for security-sensitive use)

Target:

  • 16 chars = ~80 bits entropy
  • Add HMAC signature to pairing-store.json
  • Rate limit: 1 attempt/second per IP/session

1.6 Security Documentation

Objective: Create formal security documentation.

Files to Create:

  • docs/security/threat-model.md - Cover channels, tools, browser, local files
  • docs/security/data-handling.md - Retention, logs, consent, export/delete
  • docs/security/security-posture.md - Public-facing security overview

Files to Modify:

  • src/commands/doctor.ts - Add security audit checks
    • Detect unencrypted credentials
    • Check for public gateway binding without auth
    • Verify pairing code entropy

How to Continue This Work

For a New Claude Code Session:

  1. Navigate to the worktree:

    cd ~/clawdbot-security
    
  2. Read this plan file:

    cat CLAWDBOT-SECURITY-PLAN.md
    
  3. Check current branch and status:

    git log --oneline -5
    git status
    
  4. Pick an IN PROGRESS or PENDING task and continue.

  5. Follow commit conventions:

    git commit -m "security: <description>
    
    Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>"
    

Parallel Work Guidelines:

  • Each task modifies different files, so parallel work is safe
  • If touching the same file, coordinate or work sequentially
  • Run npx vitest run <path> after changes to verify tests pass

Testing Commands

# Run specific test file
npx vitest run src/gateway/chat-sanitize.test.ts
npx vitest run src/infra/exec-blocklist.test.ts
npx vitest run src/infra/secrets-manager.test.ts

# Run all tests
pnpm test

# Type check
pnpm build
