A WOPI token carries the user's credentials to the editor server and
stayed valid for its whole six-hour lifetime, so an editor opened
before signing out could still read and save the document afterwards.
Each token now records the browser (a random id in an HttpOnly cookie,
hashed) and account slot that opened it. Signing out records a
revocation time for that browser and slot, or for every slot on a full
sign-out, and WOPI calls with a token minted before it are refused.
Signing out on another device leaves this browser's editors alone.
Revocations live in the state directory, so they survive a restart and
reach replicas sharing the state volume, and are dropped once the
tokens they cover have expired.
An impersonation handoff sealed `<target>%<master>` and the master
password into the session cookie, and `PUT /api/auth/session` hands that
cookie's contents to the browser on every restore. Anyone who received
a handoff could read a credential that signs in as every mailbox and
into Stalwart administration, with no expiry and no audit trail.
The impersonate route now uses the master credential server-side, once,
to create an app password on the target mailbox that expires after
8 hours. Only that app password reaches the cookies. Signing out
revokes it through a sealed grant cookie, and PUT refuses any session
that still holds the configured master password, so cookies minted
before this change are dropped instead of returned.
- Add AccountSwitcher component for managing user accounts with UI for switching, adding, and logging out.
- Create account state manager to handle snapshots of account-specific states for efficient switching.
- Introduce utility functions for account management, including ID generation and avatar color assignment.
- Implement Zustand store for account management, supporting addition, removal, and state retrieval of accounts.
