Adds an IFRAME_CSP environment variable that injects a Content-Security-Policy
<meta> tag into all srcdoc iframes rendering untrusted content:
- Artifacts (LLM-generated HTML previews)
- FullHeightIframe (tool/embed output)
- FilePreview (user-uploaded HTML files)
- CitationModal (RAG document HTML)
Shared utility in src/lib/utils/csp.ts handles injection with HTML-safe
attribute escaping. URL-based iframes (src=) are correctly excluded.
Env-var only — no PersistentConfig, no admin UI, no DB. Set once at deploy
time, requires restart. Empty string (default) means no CSP restriction.
New **pt-BR** translations for items introduced in the latest releases, plus a consistency/quality pass across existing strings (grammar, tone, capitalization, pluralization). Placeholders and hotkeys preserved. No logic changes.
* fix: gate public sharing of calendars behind sharing.public_calendars permission
The calendar router did not call filter_allowed_access_grants on either the
create or update endpoint, while every other shareable resource in the
codebase (channels, knowledge, models, notes, prompts, skills, tools) does.
A verified non-admin owner could therefore attach
`{"principal_type":"user","principal_id":"*","permission":"read"|"write"}`
to their own calendar in the create or update payload and have it persisted
unfiltered. Any other verified user with the (default-on) features.calendar
permission could then read or, for write grants, write events on it via the
existing /events* endpoints, bypassing the per-user sharing.public_<X>
permission gate the rest of the resource cohort enforces.
Three changes:
- config.py: add USER_PERMISSIONS_CALENDAR_ALLOW_PUBLIC_SHARING (default
False, env-overridable) and surface it in DEFAULT_USER_PERMISSIONS
['sharing']['public_calendars'] so admins can grant it per group via the
same UI used for notes/models/etc.
- routers/calendar.py: import filter_allowed_access_grants and call it in
create_calendar with the new sharing.public_calendars key, identical to
the channel router's pattern.
- routers/calendar.py: call filter_allowed_access_grants in update_calendar
too. The pre-existing owner-only gate at L350 only restricts WHO may
change grants; the new filter restricts WHICH grants they may set, so a
non-admin owner cannot make their own calendar publicly readable or
writable without the corresponding sharing permission.
Same shape as GHSA-7rjh-px4v-5w55 (channels). Reported by Matteo Panzeri.

* fix: expose public_calendars + features.calendar through admin permissions surface
The earlier commit added DEFAULT_USER_PERMISSIONS['sharing']['public_calendars']
and the runtime filter call, but the new key was not yet plumbed through the
admin /users/default/permissions endpoint. Without these changes the toggle
would round-trip as silently dropped:
- routers/users.py SharingPermissions: any payload POSTed to
/default/permissions ran through `form_data.model_dump()`, and Pydantic
drops fields not declared on the model. The new public_calendars key
would have been stripped on every save, leaving admins unable to grant
the permission via the UI even though the runtime filter would honor it.
- src/lib/constants/permissions.ts: the frontend's DEFAULT_PERMISSIONS dict
is the seed shape used by the admin Groups Permissions panel; without
the new key it could not bind a Switch component to it.
- Permissions.svelte: add a Calendars Public Sharing toggle alongside the
Notes/Chats Public Sharing toggles, gated on the existing
features.calendar flag (matches the pattern used for notes/chats).
Also closes a pre-existing parity gap on features.calendar: DEFAULT_USER_
PERMISSIONS['features']['calendar'] has existed since the calendar feature
shipped, and Permissions.svelte already renders a Calendar feature toggle,
but FeaturesPermissions Pydantic and the frontend defaults never knew
about it. Adding it everywhere completes the round-trip so admin saves no
longer silently drop the calendar feature flag either.

* refac(routers): reject external URLs in profile/model image handlers
* refac(ui): centralize image URL validation in safeImageUrl helper
* refac(auths): make signout POST-only
* refac: gate external profile image redirect behind ENABLE_PROFILE_IMAGE_URL_FORWARDING
Restore the 302 redirect for external http(s) profile image URLs in
the user and model profile-image endpoints, but gate it behind a new
ENABLE_PROFILE_IMAGE_URL_FORWARDING env flag (default: True).
Existing deployments that rely on external profile image forwarding
continue to work unchanged. Operators who want to suppress the
redirect (to prevent client-side IP/UA/Referer leaks) can set the
flag to False.
Convert the /chats/all endpoint from loading all user chats into memory
at once to a streaming NDJSON response that fetches chats in batches of
100. This prevents Out-of-Memory crashes for users with large chat
histories.
Backend: Added async generator that paginates through chats with
short-lived DB sessions per batch (critical for SQLite lock release).
Frontend: Updated getAllChats to consume the NDJSON stream via
ReadableStream reader, accumulating results for the export file.
