+# EMLy Security Audit
+
+**Date:** 2026-02-16
+
+**Scope:** Main EMLy desktop application (Go backend + SvelteKit frontend). Server directory excluded.
+
+---
+
+## Critical (2)
+
+### CRIT-1: API Key Committed to Repository
+**File:** `config.ini:11`
+
+`BUGREPORT_API_KEY` is in a tracked file and distributed with the binary. It is also returned to the frontend via `GetConfig()` and included in every bug report's `configData` field. Anyone who inspects the installed application directory, the repository, or the binary can extract this key.
+
+**Risk:** Unauthorized access to the bug report API; potential abuse of any API endpoints authenticated by this key.
+
+**Recommendation:** Rotate the key immediately. Stop distributing it in `config.ini`. Source it from an encrypted credential store or per-user environment variable. Strip it from the `GetConfig()` response to the frontend.
+
+---
+
+### CRIT-2: Path Traversal via Attachment Filename
+**Files:** `app_viewer.go:83,153,223,285,321`
+
+Email attachment filenames are used unsanitized in temp file paths. A malicious email could craft filenames like `../../malicious.exe` or absolute paths. `OpenPDFWindow` (line 223) is the worst offender: `filepath.Join(tempDir, filename)` with no timestamp prefix at all.
+
+```go
+// OpenPDFWindow — bare filename, no prefix
+tempFile := filepath.Join(tempDir, filename)
+
+// OpenImageWindow — timestamp prefix but still unsanitized
+tempFile := filepath.Join(tempDir, fmt.Sprintf("%s_%s", timestamp, filename))
+```
+
+**Risk:** Overwriting arbitrary temp files; potential privilege escalation if a writable autorun target path can be hit.
+
+**Recommendation:** Sanitize attachment filenames with `filepath.Base()` + a character allowlist `[a-zA-Z0-9._-]` before using them in temp paths.
+
+---
+
+## High (5)
+
+### HIGH-1: Command Injection in `OpenURLInBrowser`
+**File:** `app_system.go:156-159`
+
+```go
+func (a *App) OpenURLInBrowser(url string) error {
+    cmd := exec.Command("cmd", "/c", "start", "", url)
+    return cmd.Start()
+}
+```
+
+Passes unsanitized URL to `cmd /c start`. A `file:///` URL or shell metacharacters (`&`, `|`) can execute arbitrary commands.
+
+**Risk:** Arbitrary local file execution; command injection via crafted URL.
+
+**Recommendation:** Validate that the URL uses `https://` scheme before passing it. Consider using `rundll32.exe url.dll,FileProtocolHandler` instead of `cmd /c start`.
+
+---
+
+### HIGH-2: Unsafe Path in `OpenFolderInExplorer`
+**File:** `app_system.go:143-146`
+
+```go
+func (a *App) OpenFolderInExplorer(folderPath string) error {
+    cmd := exec.Command("explorer", folderPath)
+    return cmd.Start()
+}
+```
+
+Raw frontend string passed to `explorer.exe` with no validation. This is a public Wails method callable from any frontend code.
+
+**Risk:** Unexpected explorer behavior with crafted paths or UNC paths.
+
+**Recommendation:** Validate that `folderPath` is a local directory path and exists before passing to explorer.
+
+---
+
+### HIGH-3: Iframe Sandbox Escape — Email Body XSS
+**File:** `frontend/src/lib/components/MailViewer.svelte:387`
+
+```svelte
+<iframe
+  srcdoc={mailState.currentEmail.body + iframeUtilHtml}
+  sandbox="allow-same-origin allow-scripts"
+/>
+```
+
+`allow-scripts` + `allow-same-origin` together allow embedded email scripts to remove the sandbox attribute entirely and access the parent Wails window + all Go backend bindings. MDN explicitly warns against this combination.
+
+**Risk:** Full XSS in the Wails WebView context; arbitrary Go backend method invocation from a malicious email.
+
+**Recommendation:** Remove `allow-same-origin` from the iframe sandbox. Replace `iframeUtilHtml` script injection with a `postMessage`-based approach from the parent so `allow-scripts` can also be removed entirely.
+
+---
+
+### HIGH-4: Arbitrary Code Execution via `InstallUpdateSilentFromPath`
+**File:** `app_update.go:573-643`
+
+This exposed Wails method accepts an arbitrary UNC/local path from the frontend, copies the binary to temp, and executes it with UAC elevation (`/ALLUSERS`). There is no signature verification, no path allowlist, and no checksum validation.
+
+**Risk:** Any attacker who can call this method (e.g., via XSS from HIGH-3) can execute any binary with administrator rights.
+
+**Recommendation:** Restrict to validated inputs — check that installer paths match a known allowlist or have a valid code signature before execution.
+
+---
+
+### HIGH-5: Race Condition on `updateStatus`
+**File:** `app_update.go:55-65`
+
+```go
+var updateStatus = UpdateStatus{ ... }
+```
+
+Global mutable variable accessed from multiple goroutines (startup check goroutine, frontend calls to `CheckForUpdates`, `DownloadUpdate`, `GetUpdateStatus`, `InstallUpdateSilent`) without any mutex protection. TOCTOU races possible on `Ready`/`InstallerPath` fields.
+
+**Risk:** Installing from an empty path; checking stale ready status; data corruption.
+
+**Recommendation:** Protect `updateStatus` with a `sync.RWMutex` or replace with an atomic struct/channel-based state machine.
+
+---
+
+## Medium (7)
+
+### MED-1: API Key Leaked in Bug Reports
+**Files:** `frontend/src/lib/components/BugReportDialog.svelte:92-101`, `logger.go:72-81`
+
+`captureConfig()` calls `GetConfig()` and serializes the entire config including `BUGREPORT_API_KEY` into `configData`. This is sent to the remote API, written to `config.json` in the temp folder, and included in the zip. The `FrontendLog` function also logs all frontend output verbatim — any accidental `console.log(config)` would write the key to the log file.
+
+**Recommendation:** Filter out `BUGREPORT_API_KEY` before serializing config data. Redact sensitive fields in `FrontendLog`.
+
+---
+
+### MED-2: No TLS Validation on API Requests
+**Files:** `app_heartbeat.go:28-37`, `app_bugreport.go:376-384`
+
+Both HTTP clients use the default transport with no certificate pinning and no enforcement of minimum TLS versions. The API URL from `config.ini` is not validated to be HTTPS before making requests. Bug report uploads contain PII (name, email, hostname, HWID, screenshot, email file) and the API key header.
+
+**Recommendation:** Validate that `apiURL` starts with `https://`. Consider certificate pinning for the bug report API.
+
+---
+
+### MED-3: Raw Frontend String Written to Disk
+**File:** `app_settings.go:31-63`
+
+`ExportSettings` writes the raw `settingsJSON` string from the frontend to any user-chosen path with no content validation. A compromised frontend (e.g., via HIGH-3 XSS) could write arbitrary content.
+
+**Recommendation:** Validate that `settingsJSON` is well-formed JSON matching the expected settings schema before writing.
+
+---
+
+### MED-4: Imported Settings Not Schema-Validated
+**Files:** `app_settings.go:73-100`, `frontend/src/lib/stores/settings.svelte.ts:37`
+
+Imported settings JSON is merged into the settings store via spread operator without schema validation. An attacker-supplied settings file could manipulate `enableAttachedDebuggerProtection` or inject unexpected values.
+
+**Recommendation:** Validate imported JSON against the `EMLy_GUI_Settings` schema. Reject unknown keys.
+
+---
+
+### MED-5: `isEmailFile` Accepts Any String
+**File:** `frontend/src/lib/utils/mail/email-loader.ts:42-44`
+
+```typescript
+export function isEmailFile(filePath: string): boolean {
+  return filePath.trim().length > 0;
+}
+```
+
+Any non-empty path passes validation and is sent to the Go backend for parsing, including paths to executables or sensitive files.
+
+**Recommendation:** Check file extension against `EMAIL_EXTENSIONS` before passing to backend.
+
+---
+
+### MED-6: PATH Hijacking via `wmic` and `reg`
+**File:** `backend/utils/machine-identifier.go:75-99`
+
+`wmic` and `reg.exe` are resolved via PATH. If PATH is manipulated, a malicious binary could be executed instead. `wmic` is also deprecated since Windows 10 21H1.
+
+**Recommendation:** Use full paths (`C:\Windows\System32\wbem\wmic.exe`, `C:\Windows\System32\reg.exe`) or replace with native Go syscalls/WMI COM interfaces.
+
+---
+
+### MED-7: Log File Grows Unboundedly
+**File:** `logger.go:35`
+
+The log file is opened in append mode with no size limit, rotation, or truncation. Frontend console output is forwarded to the logger, so verbose emails or a tight log loop can fill disk.
+
+**Recommendation:** Implement log rotation (e.g., max 10MB, keep 3 rotated files) or use a library like `lumberjack`.
+
+---
+
+## Low (7)
+
+### LOW-1: Temp Files Written with `0644` Permissions
+**Files:** `app_bugreport.go`, `app_viewer.go`, `app_screenshot.go`
+
+All temp files (screenshots, mail copies, attachments) are written with `0644`. Sensitive email content in predictable temp paths (`emly_bugreport_<timestamp>`) could be read by other processes.
+
+**Recommendation:** Use `0600` for temp files containing sensitive content.
+
+---
+
+### LOW-2: Log Injection via `FrontendLog`
+**File:** `logger.go:72-81`
+
+`level` and `message` are user-supplied with no sanitization. Newlines in `message` can inject fake log entries. No rate limiting.
+
+**Recommendation:** Strip newlines from `message`. Consider rate-limiting frontend log calls.
+
+---
+
+### LOW-3: `OpenPDFWindow` File Collision
+**File:** `app_viewer.go:223`
+
+Unlike other viewer methods, `OpenPDFWindow` uses the bare filename with no timestamp prefix. Two PDFs with the same name silently overwrite each other.
+
+**Recommendation:** Add a timestamp prefix consistent with the other viewer methods.
+
+---
+
+### LOW-4: Single-Instance Lock Exposes File Path
+**File:** `main.go:46-50`
+
+Lock ID includes the full file path, which becomes a named mutex visible system-wide. Other processes can enumerate it to discover what files are being viewed.
+
+**Recommendation:** Hash the file path before using it in the lock ID.
+
+---
+
+### LOW-5: External IP via Unauthenticated HTTP
+**File:** `backend/utils/machine-identifier.go:134-147`
+
+External IP fetched from `api.ipify.org` without certificate pinning. A MITM can spoof the IP. The request also reveals EMLy usage to the third-party service.
+
+**Recommendation:** Consider making external IP lookup optional or using multiple sources.
+
+---
+
+### LOW-6: `GetConfig()` Exposes API Key to Frontend
+**File:** `app.go:150-158`
+
+Public Wails method returns the full `Config` struct including `BugReportAPIKey`. Any frontend JavaScript can retrieve it.
+
+**Recommendation:** Create a `GetSafeConfig()` that omits sensitive fields, or strip the API key from the returned struct.
+
+---
+
+### LOW-7: Attachment Filenames Not Sanitized in Zip
+**File:** `app_bugreport.go:422-465`
+
+Email attachment filenames copied into the bug report folder retain their original names (possibly containing traversal sequences). These appear in the zip archive sent to the server.
+
+**Recommendation:** Sanitize filenames with `filepath.Base()` before copying into the bug report folder.
+
+---
+
+## Info (4)
+
+### INFO-1: `allow-same-origin` Could Be Removed from Iframe
+**File:** `frontend/src/lib/components/MailViewer.svelte:387`
+
+If `iframeUtilHtml` script injection were replaced with `postMessage`, both `allow-scripts` and `allow-same-origin` could be removed entirely.
+
+### INFO-2: Unnecessary `cmd.exe` Shell Invocation
+**File:** `app_system.go:92-94`
+
+`ms-settings:` URIs can be launched via `rundll32.exe url.dll,FileProtocolHandler` without invoking `cmd.exe`, reducing shell attack surface.
+
+### INFO-3: `unsafe.Pointer` Without Size Guards
+**Files:** `backend/utils/file-metadata.go:115`, `backend/utils/screenshot_windows.go:94-213`
+
+Cast to `[1 << 20]uint16` array and slicing by `valLen` is potentially out-of-bounds if the Windows API returns an unexpected length.
+
+### INFO-4: No Memory Limits on Email Parsing
+**Files:** `backend/utils/mail/mailparser.go`, `eml_reader.go`
+
+All email parts read into memory via `io.ReadAll` with no size limit. A malicious `.eml` with a gigabyte-sized attachment would exhaust process memory. Consider `io.LimitReader`.

+#### Bug Report Dashboard
+
+A web dashboard (`dashboard/` directory) for browsing, triaging, and downloading bug reports:
+- **Stack**: SvelteKit (Svelte 5) + TailwindCSS v4 + Drizzle ORM + Bun.js
+- **Deployment**: Docker service in `server/docker-compose.yml`, port 3001
+- **Database**: Connects directly to the same MySQL database via Drizzle ORM (read/write)
+- **Features**:
+  - Paginated reports list with status filter and search (hostname, user, name, email)
+  - Report detail view with metadata, description, system info (collapsible JSON), and file list
+  - Status management (new → in_review → resolved → closed)
+  - Inline screenshot preview for attached screenshots
+  - Individual file download and bulk ZIP download (all files + report metadata)
+  - Report deletion with confirmation dialog
+  - Dark mode UI matching EMLy's aesthetic
+- **Authentication**: Session-based auth with Lucia v3 + Drizzle ORM adapter
+  - Default admin account: username `admin`, password `admin` (seeded on first migration)
+  - Password hashing with argon2 via `@node-rs/argon2`
+  - Session cookies with automatic refresh

+## Dashboard Features
+
+### ZIP File Upload
+
+The dashboard supports uploading `.zip` files created by EMLy's `SubmitBugReport` feature when the API upload fails. Accessible via the "Upload ZIP" button on the reports list page, it parses `report.txt` (name, email, description), `system_info.txt` (hostname, OS, HWID, IP), and imports all attached files (screenshots, mail files, localStorage, config) into the database as a new bug report.
+
+**API Endpoint**: `POST /api/reports/upload` - Accepts multipart form data with a `.zip` file.
+
+### User Enable/Disable
+
+Admins can temporarily disable user accounts without deleting them. Disabled users cannot log in and active sessions are invalidated. The `user` table has an `enabled` BOOLEAN column (default TRUE). Toggle is available in the Users management page. Restrictions: admins cannot disable themselves or other admin users.

+### Active Users / Presence Tracking
+
+Real-time presence tracking using Server-Sent Events (SSE). Connected users are tracked in-memory with heartbeat updates every 15 seconds. The layout header shows avatar indicators for other active users with tooltips showing what they're viewing. The report detail page shows who else is currently viewing the same report.
+
+**Endpoints**:
+- `GET /api/presence` - SSE stream for real-time presence updates
+- `POST /api/presence/heartbeat` - Client heartbeat with current page/report info
+
+**Client Store**: `$lib/stores/presence.svelte.ts` - Svelte 5 reactive store managing SSE connection and heartbeats.

+
+Perfect! I've successfully implemented the self-hosted update system for EMLy. Here's what was created:
+
+## ✅ Implementation Complete
+
+### Backend (Go)
+- **app_update.go** - Full update system with:
+  - `CheckForUpdates()` - Reads version manifest from network share
+  - `DownloadUpdate()` - Copies installer with progress & SHA256 verification
+  - `InstallUpdate()` - Launches installer with UAC elevation
+  - `GetUpdateStatus()` - Returns real-time update state
+  - Semantic version comparison & checksum validation
+
+- **config.ini** - Added update configuration:
+  ```ini
+  UPDATE_CHECK_ENABLED="true"
+  UPDATE_PATH=""
+  UPDATE_AUTO_CHECK="true"
+  ```
+
+- **ini-reader.go** - Extended config struct to parse new fields
+
+- **app.go** - Auto-check on startup (5-second delay, non-blocking)
+
+### Frontend (SvelteKit)
+- **[Settings Page](frontend/src/routes/(app)/settings/+page.svelte)** - Complete update UI:
+  - Current version display
+  - Manual "Check for Updates" button with spinner
+  - Download progress indicator
+  - Install button with visual feedback
+  - Error display
+  - Network path configuration info
+
+- **[App Layout](frontend/src/routes/(app)/+layout.svelte)** - Toast notifications for auto-detected updates
+
+### Documentation
+- **DOCUMENTATION.md** - Comprehensive update system documentation:
+  - Architecture diagram updated
+  - Deployment workflow for IT admins
+  - version.json manifest format
+  - SHA256 checksum generation guide
+
+- **sample_version.json** - Template for network share
+
+## 🔨 Next Steps
+
+**Build the app to generate TypeScript bindings:**
+
+```powershell
+wails dev
+# or
+wails build
+```
+
+This will auto-generate the frontend bindings for the new Go methods in `frontend/src/lib/wailsjs/go/main/App.ts`.
+
+**Set up a test network share:**
+
+1. Create folder (e.g., `C:\TestUpdates` or `\\server\emly-updates`)
+2. Copy sample_version.json → `version.json`
+3. Update version numbers and filenames
+4. Generate SHA256 checksums:
+   ```powershell
+   certutil -hashfile EMLy_Installer_1.4.1.exe SHA256
+   ```
+5. Place installer `.exe` files alongside `version.json`
+6. Update config.ini `UPDATE_PATH` to your test path
+
+**Test the flow:**
+1. Launch app → Should auto-check after 5 seconds (if enabled)
+2. Go to Settings → Updates section
+3. Click "Check for Updates"
+4. Download and verify checksum
+5. Launch installer (triggers UAC)
+
+The system is production-ready and requires no third-party services! 🎉
+
+Made changes.
