GHOSTPORT OS

PATCH & FEATURE LOG

Published: March 24, 2026 • Covering: Pre-Audit + Rounds 1–13 + Theme Engine + Fleet Integration + Family Shield + Full-Stack Hardening + Investor Portal

Over the course of eight days (March 17–24, 2026), we conducted a comprehensive multi-round security audit of every component in GhostPort OS — from the Express API server and frontend SPA to nftables firewall profiles, shell scripts, systemd services, and the EC2 fleet infrastructure. This log documents 242 bugs found, 113 patched across 13 audit rounds, a brand new color theming engine with RGB breathing mode, Family Shield parental controls with DNS + IP-level blocking, the Phase 2 fleet integration system with Stripe subscriptions, and a full-stack hardening pass across both the Pi and EC2.

Round 13 — Investor Portal & Repo Sync — March 24, 2026

Investor page hardening, SEO schema, animation reliability, nftables repo sync • 5 issues found, 5 patched

PATCHED

CRITICAL

HIGH

MEDIUM

#	Severity	System	Bug	Fix
1	HIGH	Investor page	`noindex, nofollow` meta tag blocking all search engine indexing — invisible to Google	Changed to `index, follow` with canonical URL and keyword meta
2	MED	Investor page	No JSON-LD structured data — search engines can’t identify organization, products, or pricing	Added `@graph` schema: Organization, WebPage, Product (3 tiers with prices)
3	MED	Investor page	Revenue counters stuck at $0K on mobile — IntersectionObserver threshold (15%) too high for tall stacked panels	Lowered threshold to 5%, removed -50px rootMargin, added 4-second fallback timer
4	MED	nftables repo	All 5 nft profiles drifted from live — repo missing IPv6 drops, QUIC block, explicit port rules, DNS prerouting, drop logging	Synced all profiles: `common.nft`, `isp.nft`, `zerotrust.nft`, `doublehop.nft`, `zhop.nft`
5	MED	Investor page	IntersectionObserver used `rootMargin: '0px 0px -50px 0px'` clipping bottom of viewport — sections near page bottom never triggered	Removed negative rootMargin so full viewport is the trigger zone

3 parallel audit agents • 68 bugs found across server, frontend, firewall, and system scripts • Automated pipeline deployment

Critical (5)

#	File	Bug
158	CRIT server.js	/api/fleet/activate unauthenticated — attacker can set all credentials and take over device before legitimate activation

Critical (11)

#	File	Bug	Fix
92–100	CRIT arsenal.js	9 XSS vulnerabilities — `data.error`, `data.status`, and speed test values injected unsanitized into innerHTML across DNS Leak, Ping, IP Leak, Speed Test, System Update, Blocked Domains, and Security Scan results	All values wrapped in `escapeHtml()`
101	CRIT server.js	Hardcoded fleet token fallback — anyone reading source can register rogue devices	Removed fallback, fleet.json required
102	CRIT gp-mode	DoubleHop/ZHop applies nftables forward-drop before wg0 exists — connectivity blackout, full LAN outage if WireGuard fails	Reordered: `start_wg0` now runs before `apply_profile`

High (10)

#	File	Bug	Fix
103	HIGH server.js:90	Family Shield IP blocks silently fail to restore on startup — `FAMILY_SHIELD_IP_RANGES` const in temporal dead zone when called	Moved startup restore code after all const declarations
104	HIGH server.js	No CSRF protection on any POST endpoint	Noted for next round — requires token infrastructure

New Feature — Family Shield (March 22, 2026)

🛡 Parental Controls with DNS + IP Blocking

Family Shield is a dual-layer parental control system that combines Pi-hole DNS filtering with nftables IP-range firewall rules. DNS blocking alone can’t stop apps like TikTok that use CDN fallbacks and hardcoded IPs — so we added firewall rules that block entire ASN-owned IP ranges at the packet level.

5 Categories — Adult Content, Gambling, Meta Apps (FB/IG/WhatsApp), TikTok, X (formerly Twitter)
DNS Blocking — Pi-hole v6 group-based filtering with 22,459+ domain blocklists per category
IP-Range Blocking — nftables sets blocking ByteDance (13 CIDR ranges), Meta (16 ranges), and X/Twitter (6 ranges) at the packet level
Per-Device Shielding — Shield specific devices without blocking yourself. DISCOVER button scans for connected clients
Master Toggle — One switch enables/disables all parental controls. Category toggles for granular control
Persistent Config — Settings saved to /etc/ghostport/family-shield.json, IP blocks restored on server restart

Family Shield — Bugs Fixed During Development

#	Severity	Component	Bug	Fix
85	HIGH	Server	Pi-hole v6 `_suggestions` API returns array format, not object — device discovery and shielding broken	Rewrote parsing for `{clients: [{addresses, names}]}` format in 3 endpoints
86	HIGH	Server	Pi-hole v6 lists API requires `?type=block` as query parameter, not in JSON body	Added query parameter to all POST/PUT list endpoint URLs
87	MED	Frontend	Toggle race condition — `load()` polling overwrites toggle state during API calls	Added `fs.busy` flag, `load()` skips when busy
88	MED	Config	`family-shield.json` owned by root, server runs as ghostport-admin	Fixed ownership with `chown ghostport-admin:ghostport-admin`
89	MED	Pi-hole	Session exhaustion — default max 16 sessions burned by debug restarts	Bumped to 64 via `pihole-FTL --config webserver.api.max_sessions 64`
90	HIGH	Pi-hole	Gravity database corruption from repeated FTL restarts — tables missing	Rebuilt gravity.db from scratch, re-added blocklists and groups
91	MED	Blocking	TikTok DNS blocking ineffective — app uses Akamai CDN fallbacks	Added nftables IP-range blocking for ByteDance ASN ranges

Phase 2 — Fleet Integration (March 21, 2026)

Heartbeat Agent (gp-heartbeat)

Systemd timer-driven agent that checks in with the EC2 fleet server every 5 minutes. Each heartbeat sends the device’s firmware version, uptime, and current mode. The fleet server responds with subscription status and any pending commands (e.g., mode change, config update).

5-minute cadence — systemd timer triggers gp-heartbeat script on a reliable interval
Payload — firmware version, system uptime, current firewall mode, device serial
Response — subscription tier + expiry, pending remote commands, firmware update availability

Install Page (/install)

Customer-facing dark-themed activation page served at /install. Users enter their license key to activate the device. The page auto-provisions the router without requiring prior authentication.

Dark-themed UI — matches the GhostPort Command Deck aesthetic
License key input — validates format client-side, submits to fleet activation endpoint
Auto-provisioning — on success, generates credentials and completes device setup

/api/fleet/activate Endpoint

No-auth device setup endpoint. Accepts a license key, registers the device with the fleet server, and returns freshly generated credentials for the customer.

No authentication required — designed for first-boot activation before any passcode exists
Auto-generates — dashboard passcode, WiFi AP password, and Pi-hole admin password
Fleet registration — sends device serial + license key to EC2 fleet API, receives subscription tier

gp-new --auto

Non-interactive factory provisioning mode for the gp-new registration script. Enables headless device setup during manufacturing or bulk deployment without manual prompts.

Non-interactive — all prompts bypassed with sane defaults or pre-configured values
Factory use case — flash, boot, auto-register, ship

Stripe Subscription Integration

Three-tier subscription model with webhook-driven license management. Stripe events flow to the EC2 fleet server, which updates each device’s subscription status. The Pi’s heartbeat agent picks up changes on its next check-in.

Basic — $5/mo — Core privacy routing, ISP + ZeroTrust modes
Phantom Guardian — $10/mo — All modes including DoubleHop VPN, kill switch, MAC randomization
Unholy Covenant — $15/mo — Full feature set: ZHop, scheduled mode switching, priority support

EC2 Fleet API Pipeline

End-to-end subscription lifecycle: Stripe webhook fires on payment events → EC2 fleet server updates the device record → Pi heartbeat picks up the new subscription status on next 5-minute check-in.

Stripe → Fleet — Webhook receiver on EC2 validates Stripe signatures, maps customer to device
Fleet → Pi — Heartbeat response includes updated subscription tier, expiry, and feature flags
Grace period — failed payments trigger a grace window before feature downgrade

New Feature — Theme Color Engine

🎨 Infinite Color Picker + RGB Breathing Mode

The GhostPort Command Deck now supports full UI color customization. Every element — accents, backgrounds, borders, text, glows — adapts to your chosen color in real time.

8 Preset Swatches — Green (default), Purple, Blue, Red, White, Cyan, Amber, and Gunmetal. One-click to apply.
Custom Color Picker — Pick literally any color. The entire UI derives backgrounds, borders, text, and glow values from your chosen hue using a real-time HSL engine.
RGB Breathing Mode — Smooth, continuous hue rotation powered by requestAnimationFrame. A sine-wave brightness pulse creates a living, breathing effect. Full spectrum rotation every ~6.5 seconds at 30fps.
Achromatic Support — Grey, white, and black colors are handled correctly. The engine passes saturation through to prevent unwanted red tinting on neutral colors.
Persistence — Your choice saves to localStorage and applies across both the login screen and dashboard. Survives page reloads and browser restarts.
Login Screen Sync — The authentication page matches your chosen theme, including RGB breathing mode. First impression matches the rest of the UI.
Migration — Users with older named theme values in localStorage are automatically migrated to the new hex-based system.

Round 7 — March 21, 2026

Script: fix-bugs-round7.py • 18 patches across 4 categories

#	Severity	File	Bug	Fix
66–80	MED	ghostport-server.js	15 endpoints exposed raw `e.message` in error responses. Child process errors could leak filesystem paths, command names, or internal system details to authenticated clients	All error responses now return generic messages ("Operation failed", "Mode switch failed", etc.). Full details logged server-side with `console.error()`
81	HIGH	ghostport-server.js	DHCP lease hostname from dnsmasq not HTML-escaped in `/api/arsenal/clients` response. A device with `<script>` in its hostname could inject into the client list UI	Wrapped hostname in `escapeHtml()`
82	MED	ghostport-server.js	`POST /api/arsenal/dnstest` had no rate limiting. Could be spammed to flood external DNS lookups and `ifconfig.me` requests, causing resource exhaustion	Added 30-second cooldown (same pattern as speedtest's 2-minute throttle)
83	HIGH	ghostport-server.js	Restore endpoint wrote directly to `/etc/ghostport/arsenal.json` without the `withArsenal()` mutex. Concurrent arsenal operations (toggle, schedule add) could corrupt the config file	Wrapped in `await withArsenal()` to serialize writes

Bug Fix — March 21, 2026 (Server Crash-Loop)

Post-Round 7 hotfix • Server crash-loop recovery

#	Severity	File	Bug	Fix
84	CRIT	ghostport-server.js	Duplicate `try{}` block in `flushTally()` from a prior round patch caused a `SyntaxError` on startup — server entered a crash-loop with 162 restarts before detection	Collapsed duplicate try blocks into a single `try/catch/finally` structure

Round 6 — March 21, 2026

Script: fix-bugs-round6.py • 9 patches across server & firewall

#	Severity	File	Bug	Fix
57	HIGH	ghostport-server.js	Schedule deletion endpoint had copy-pasted `finally` block from Lynis scanner — resetting unrelated `lynisScanRunning` flag and returning wrong error message ("Security scan failed")	Removed wrong `finally` block, fixed error message to "Failed to delete schedule"
58	HIGH	ghostport-server.js	6 locations used predictable temp file names in `/tmp/` (e.g. `/tmp/gp-hostapd.conf`) — symlink attack vector on world-writable directory	Added `gpTmpFile()` helper using `crypto.randomBytes(8)` for unique names. Applied to hostapd, WireGuard, restore, MAC randomization, and schedule writes
59	MED	ghostport-server.js	Restore endpoint exposed `e.message` in error response — could leak filesystem paths or command output	Replaced with generic "Config restore failed" message, logs details server-side
60	MED	ghostport-server.js	DNS leak check used `curl -4` (IPv4 only) — wouldn't detect IPv6 DNS leaks	Switched to dual-stack `curl -s` to catch both v4 and v6 leak types
61	LOW	ghostport-server.js	Gateway and speedtest ping commands passed IPs without shell quoting	Added single-quote wrapping around interpolated IP variables for defense-in-depth
62	MED	ghostport-server.js	Restore endpoint used `systemctl restart wg-quick@wg0` but gp-mode manages wg0 directly via `ip`/`wg` commands — service conflicts with existing interface	Replaced with `gp-mode` reapply for consistency with how WireGuard is actually managed
63	MED	ghostport-server.js	Kill switch nftables rules only allowed port 4200 (HTTP dashboard) but not 4201 (HTTPS) — would lose dashboard access over HTTPS during kill switch activation	Added port 4201 to kill switch accept rules
64	LOW	public/index.html	Three CSS classes (`.mode-desc`, `.log-msg.info`, `.arsenal-desc`) used hardcoded green hex values that didn't respond to theme color switching	Replaced `#6a9a6a` and `#5a8a5a` with `var(--text-dim)`
65	LOW	common.nft	Ports 80 and 443 had accept rules open to all interfaces — redundant since policy is `accept` but misleading	Already cleaned up (found pre-fixed during verification)

Round 5b — March 19, 2026

Script: fix-bugs-round5b.py • 9 bugs across 5 files • Deep audit of previously unaudited files

#	Severity	File	Bug	Fix
49	CRIT	public/pwa.html	XSS in setup summary — user-supplied name and email interpolated into innerHTML unescaped	Added `esc()` helper, escaped name, serial, and email fields
50	CRIT	public/pwa.html	XSS in log rendering — `l.msg` inserted into innerHTML without escaping	Wrapped in `esc()`
51	HIGH	public/da.html	XSS in QA error handler — `e.message` rendered as raw HTML	Added `esc()` helper, escaped error message
52	HIGH	public/da.html	XSS in log entries — `l.message` and `l.timestamp` unescaped	Escaped both fields
53	HIGH	public/da.html	XSS in device info — all API-sourced device fields rendered as raw HTML	Escaped labels and values
54	HIGH	public/da.html	XSS in QA checklist — `c.name` and `c.detail` unescaped in innerHTML	Escaped both fields
55	HIGH	isp.nft	Missing IPv6 drop in forward chain — clients can bypass routing via IPv6 tunnels	Added `meta nfproto ipv6 counter drop` to forward chain
56	HIGH	zerotrust.nft	Missing IPv6 drop in forward chain — DNS lock bypass via IPv6	Added `meta nfproto ipv6 counter drop` to forward chain
56b	MED	gp-dns-upstream	Silent failures — no error reporting if config file missing or sed replacement fails	Added file existence check and post-sed verification with error output

Script: fix-bugs-round5.py • 7 bugs, 10 patches

#	Severity	File	Bug	Fix
42	CRIT	ghostport-server.js	`ispIpCacheTime` used but never declared — DNS leak monitor crashes with ReferenceError on first run	Added `let ispIpCacheTime = 0` declaration
43	HIGH	ghostport-server.js	No rate limit on `/api/tools/speedtest` — DoS vector via repeated 60-120 second system commands	Added 2-minute cooldown between speed tests
44	HIGH	ghostport-server.js	Lynis scan flag `lynisScanRunning` not reset on exception — one crash permanently locks scanning	Moved reset to `finally` block
45	MED	ghostport-server.js	Trouble ticket description/contact accept newlines — webhook message injection	Strip `\r\n`, cap description at 500 chars, contact at 100
46	MED	ghostport-server.js	Error responses leak internal paths, stderr, and webhook URLs	Sanitized all error messages to generic strings
47	LOW	ghostport-server.js	`/login/` with trailing slash returns 404	Changed route to regex: `/^\/login\/?$/`

33	HIGH	ghostport-server.js	`stopKillSwitch()` reads mode from file and passes to `exec()` without validation — command injection via compromised modefile	Added whitelist validation before execution
34	HIGH	ghostport-server.js	`startKillSwitch()` recovery path same issue	Added whitelist validation
35	HIGH	ghostport-server.js	WireGuard stats: `parseInt(rx \|\| 0)` returns NaN on corrupted data; no array bounds check on tab-split output	Added `parseInt(x, 10) \|\| 0` fallback and `filter(line => parts.length >= 7)`
36	MED	ghostport-server.js	Restore endpoint: `fs.unlinkSync(tmpWg)` crashes on permission error	Wrapped in try-catch
37	MED	ghostport-server.js	Restore endpoint: `fs.unlinkSync(tmpHap)` same issue	Wrapped in try-catch
38	MED	ghostport-server.js	Kill switch: concurrent toggle + monitor causes state mismatch if interval becomes stale	Clears stale interval before starting new one

7	MED	ghostport-server.js	Hostapd config read via shell `cat` — unnecessary shell invocation	Switched to `fs.readFileSync` with sudo fallback
8	CRIT	gp-mode / nftables	DNS leak monitor nftables rules used invalid mixed tcp/udp syntax	Split into separate accept+drop rules matching kill switch pattern
9	CRIT	gp-mode / gp-dns-upstream	DNS upstream switch called before mode file update — reads OLD mode, applies wrong DNS	Moved `gp-dns-upstream` call to after modefile write in every mode case

Hardening Roadmap

Tier 1 — Immediate (30 minutes)

Enable unattended-upgrades on Pi — auto-install security patches
Set PermitRootLogin no explicitly in sshd_config
Enable rp_filter = 1 — prevent IP spoofing on LAN
Add logrotate for ghostport services
Enable EBS encryption on next EC2 AMI

Tier 2 — This Month

Automated S3 backups — fleet DB, configs, certs
Install auditd on both systems — audit trail for compliance
CSRF tokens on state-changing endpoints
Remove CSP unsafe-inline
Write incident response playbook
Dependency audit (npm audit, pip audit)

Tier 3 — Before Enterprise Sales

SOC 2 Type I readiness assessment
SIEM / centralized logging
File integrity monitoring (AIDE or OSSEC)
Third-party penetration test
Privacy policy + terms of service (legal review)
SD card encryption (LUKS) for customer devices
