After a successful password change, revoke all browser sessions for the
same user except the one that submitted the request. This prevents stale
sessions on other devices from remaining valid after credentials are
updated.
Keep API-token behavior unchanged. The current browser session is
preserved so the user can continue from the tab that changed the
password.
Add focused regression tests for preserving the current session, revoking
other sessions, persisting revocation, and avoiding revocation when the
current password is incorrect.
`core.middleware.require_admin` grants admin to any request whose
`request.state.current_user == "internal-tool"` — the sentinel meant only
for the in-process tool-loopback path. But the normal cookie auth path
(app.py) sets `current_user` to the raw username, and neither `create_user`
nor the signup route reserved that name. As a result an account literally
named "internal-tool" was silently treated as admin by every
`require_admin`-gated route. With self-service signup enabled this is an
anonymous -> admin privilege escalation.
Reserve the full synthetic-owner set the codebase already special-cases —
"internal-tool", "api", "demo", "system" (see `_SYNTHETIC_OWNERS` in
routes/assistant_routes.py and the matching guards in src/task_scheduler.py
and routes/research_routes.py). "api" collides with the bearer-token owner
sentinel; "demo"/"system" would leave a real account denied an assistant
and inconsistently owner-scoped.
Refuse to create or rename into any reserved name (case/space-normalized),
and reject empty usernames while we're here. Adds a regression test.

verify_password() and create_session() both call .strip().lower() on
the incoming username, but _load() stored keys verbatim from auth.json.
Any mixed-case key (e.g. written by manual edit or a future migration)
would never match, producing a permanent 'Invalid credentials' error.
Fix: lowercase all keys at load time so the in-memory dict always
matches what the login path expects.
Fixes#423
The email auto-calendar pass (settings.email_auto_calendar / the
extract_email_events task) scans recently received mail and lets an LLM
create / update / cancel calendar events. Two problems made it a cross-tenant,
remotely triggerable hole:
1. No owner scoping. _auto_summarize_pass(account_id=None) fans out over EVERY
enabled account of EVERY user. For each message it fetched an upcoming-events
snapshot with NO owner filter (all tenants' events) and handed those uids +
titles to the extraction LLM, then executed the model's ops via
do_manage_calendar(...) with owner=None. do_manage_calendar only filters by
owner when owner is not None, so create/update/delete ran across ALL users'
calendars. Net: every user's event titles/times were disclosed to the model,
and the model could cancel/move/duplicate any tenant's events by uid.
2. No prompt-injection wrapping. The raw email From/Subject/body were
interpolated straight into an instruction-shaped extraction prompt (unlike
the chat path, which wraps external text via src/prompt_security). Anyone
who can email a user whose instance has auto-calendar enabled could inject
operations: create attacker-controlled "meeting" events (the path even
auto-harvests URLs from the body into the event location/description — a
phishing primitive) or cancel/modify the victim's real events, with zero
human in the loop.
Fix:
- Add core.database.get_upcoming_events(owner) and use it for the snapshot, so
the LLM only ever sees the processed account owner's events.
- Look up the EmailAccount owner in _auto_summarize_pass_single and pass owner=
to every do_manage_calendar call, so create/update/delete are scoped to that
user (owner=None stays the single-user / legacy escape hatch).
- Tell the extraction model the email is untrusted data and not to follow
instructions inside it (defense-in-depth against injection).
Add tests/test_calendar_owner_scope.py: get_upcoming_events returns only the
given owner's events (and everything when owner is None). Fails against the old
unscoped query.
Hardens issues found in a security review of the current tree (separate from
the cookbook SSH PR):
- Email thread rendering (static/js/emailLibrary.js): the flat read path runs
inbound HTML through the allowlist sanitizer, but the two threaded paths
(_renderTurnsAsBubbles / _renderTurnsFromServer — the default view) injected
server-parsed `body_html` raw into the DOM. A crafted inbound email could
inject arbitrary markup (phishing/form/credential-capture/tracking; full XSS
if a deployment relaxes the script CSP). Now sanitized on all paths.
- Attachment extraction (routes/email_routes.py, routes/email_helpers.py): the
on-disk extraction dir was `ATTACHMENTS_DIR / f"{folder}_{uid}"` with
user-controlled folder/uid and no containment, so a folder like `../../tmp`
could escape ATTACHMENTS_DIR. New attachment_extract_dir() flattens both to a
single safe segment and asserts containment.
- Diagnostics routes (routes/diagnostics_routes.py): /api/db/stats,
/api/rag/stats, /api/test/youtube, /api/test-research relied only on the
global session check (any logged-in user). Now require_admin-gated.
- Defense-in-depth HTML escaping: session HTML export escapes the session name
(routes/session_routes.py); the MCP OAuth page escapes the reflected Host
header / server_id (routes/mcp_routes.py).
- Internal-tool token now compared with secrets.compare_digest (constant time)
in core/middleware.py and app.py.
Adds regression tests in tests/test_security_regressions.py.
chat_routes.py persisted a session's "mode" in three best-effort spots —
reading the current mode, writing the effective mode, and setting
research_pending on the stream path. Each opened a session with SessionLocal()
and called .close() as the LAST statement inside a try/except, so if anything
before close() raised (e.g. a SQLite "database is locked" under concurrent chat
streams) the except only logged and the connection was never returned to the
pool.
DATABASE_URL defaults to file-backed SQLite, whose engine uses SQLAlchemy's
default QueuePool (5 connections + 10 overflow). Repeated leaks on these hot
paths exhaust the pool; later requests then block for pool_timeout and fail
with "QueuePool limit ... reached", taking the app down until restart.
Move the logic into two best-effort helpers in core.database, next to the
existing session helpers (update_session_last_accessed, get_session_by_id):
- get_session_mode(session_id) -> Optional[str]
- set_session_mode(session_id, mode) -> bool
Both route through the existing get_db_session() context manager, which commits
on success, rolls back on error, and always closes in a finally, so the
connection is returned to the pool on every path. chat_routes.py now calls
these instead of hand-rolling sessions, also removing three copies of the same
try/except.
Add tests/test_session_mode_helpers.py: the helpers commit+close on success
and, on a mid-operation DB error, swallow + roll back + close (no leak). The
error-path tests fail against the old close()-inside-try pattern.
