The origin gate in the proxy only covered `/api/auth/*`. The JMAP
passthrough, `/api/settings`, `/api/wopi/launch`,
`/api/plugin-approval-status`, `/api/fetch-ical`, `/api/translate`,
`/api/caldav/discover`, `/api/calendar-agenda` and `/api/webdav` all act
with the session cookie and had no origin check. A page on a same-site
sibling origin receives SameSite=Lax cookies, so it could run arbitrary
JMAP as the signed-in user, including sharing mailboxes to a third
account.
The proxy now gates every `/api/` route except the WOPI file endpoints
the office editor calls server-to-server, and each of these handlers
checks again. The proxy also decides on the decoded path, so an escaped
spelling such as `/api/%61uth/session` no longer skips the gate.
Drops the 0.15 REST management API and routes all account/auth/crypto/
principal operations through Stalwart 0.16's schema-driven JMAP
endpoint via a single passthrough (/api/account/stalwart/jmap).
- New client helper `stalwartJmap` + typed `requireResult`
- account-security-store rewritten against x:AccountPassword, x:AppPassword,
x:AccountSettings, x:Account (with currentSecret for TOTP ops)
- Client-side TOTP setup via `otpauth`; server-generated app password
secrets shown once on create
- Admin check switched to /api/account permissions
(sysAccountQuery/sysTenantQuery/sysSystemSettingsGet)
- Removed sieve vacation-overwrite workaround (fixed upstream #1251)
- Deleted old REST routes, StalwartClient, stale tests; added new
tests for passthrough + store
Add a new Files section powered by WebDAV for browsing, uploading,
downloading, renaming, and deleting files and folders.
New features:
- WebDAV file browser with grid/list views and breadcrumb navigation
- File upload (drag-and-drop and button), folder creation, rename, delete
- File preview modals for images and other file types
- WebDAV proxy API route to handle authentication
- Navigation rail entry for Files (auto-hidden when WebDAV is unsupported)
Auth improvements:
- Fix premature redirects on calendar, contacts, and settings pages by
adding explicit auth check on mount before redirecting to login
- Persist active settings tab in localStorage
Other:
- Expose getAuthHeader() and getServerUrl() on JMAPClient
- Add WebDAV store with connection testing and capability detection
- Add i18n translations for file browser in all 8 locales (de, en, es,
fr, it, ja, nl, pt)
