lebaudantoine b593516802 🔒️(backend) derive connection-test room max age from token TTL
Refactor CONNECTION_TEST_ROOM_MAX_AGE_SECONDS so it is no longer an
independent setting but a quantity derived from (or added on top of)
the token TTL.

This prevents a misconfiguration where the token would outlive the
delete-room callback. In that case, an attacker holding a valid
token could recreate the room after the callback fired and escape
the intended cleanup.

Arnaud Robin b01a47bfd7 (backend) add connection-test API
Currently users have no way to reliably test their connection before
joining a room. To address this, we plan to build a connection-test
page.

The testing requires a dedicated LiveKit token, issued without going
through the room API, which is tied to registered meetings, lobby
rules, and longer-lived access tokens.

Introduce a new viewset for all diagnostics-related features. The
first route issues a token for diagnostics, even for anonymous
users. Each request creates a new dedicated room so users never
share the same LiveKit room during tests. Tokens are short-lived
(default 10 minutes) to limit reuse, and the endpoint is throttled
to prevent abuse.

A Celery worker also schedules a callback that deletes the room
after a certain delay, in every case.

lebaudantoine ac8eae7295 (backend) apply user preferences on unconfigured room creation
Update the API so that, when a user creates a new meeting without
passing an explicit configuration, the user's persisted preferences
are applied as defaults.

This allows a user to, for example, enable the waiting room by
default on every meeting they create.

lebaudantoine 2e509eff28 (backend) persist user preferences for room defaults on the User model
Add attributes on the User model to persist per-user preferences for
the default link access level and the default room configuration.

The frontend will let users update these preferences and then reuse
them when generating a link through the webapp.

Persisting them on the backend (rather than in application memory
only) ensures the preferences survive across sessions and devices.

lebaudantoine 8b198726e9 (backend) add roomkit viewset to start a room without WebRTC join
Introduce a new viewset that lets the roomkit start a room even when
no WebRTC participant has joined yet.

This is a first entry point that will be extended over time with
more actions a roomkit needs to be able to trigger.

Known limitations:

* The responsibility around SIP rules is currently split between
  the telephony feature and the roomkit one. This may need a
  refactor later on to consolidate ownership in a single place.
* The default throttle might be too low for production usage and
  will likely need to be revisited.

lebaudantoine dd3f23b1bf 🐛(backend) allow any string as sub in the API serializer
The API serializer was too restrictive on the `sub` field, expecting
a UUID. This worked in our development and production setups because
our Keycloak is configured to emit UUID subs, but it broke for other
providers.

Per the OIDC spec and the DB model, `sub` can be any string. Align
the serializer with this and accept arbitrary string values.

Fixes #1525.

lebaudantoine 82aafa2030 ♻️(frontend) derive is_administrable from participant metadata
The is_administrable flag was previously read from the room API
response through the room serializer, giving the frontend static
information about the user's rights.

Refactor the frontend so it derives this flag from the participant
role carried in the participant metadata instead.

Two benefits:

* The flag now updates live along with the participant
  attributes/metadata, so role changes are reflected immediately.
* It removes the duplication between the API response and the
  metadata, which both used to determine the user's capabilities.

lebaudantoine 65172447ca ♻️(backend) pass the participant role in the LiveKit token
The backend previously passed an abstract is_admin_or_owner boolean
flag in the LiveKit token. That kept the frontend minimalistic and
saved it from having to handle role comparisons.

As we introduce more features that need to distinguish between the
room owner and admins, refactor the token to carry the role
directly. The frontend can then derive the relevant flags from a
richer piece of information.

lebaudantoine 71d76abc0f (backend) add endpoint to update a participant role during a meeting

lebaudantoine 47f3da4153 ️(backend) add permission class checking the user is in the call
Introduce a new permission class that verifies the caller making a
request is both authenticated and actually present in the call.

It will be used to gate actions that require the user to be live in
the room, for example:

* allowing someone in from the waiting room
* promoting another participant to a different role

More generally, this covers every action where, for security
reasons, we need to make sure the user is truly present in the call
and that someone is not reusing their cookie as an API key.

lebaudantoine f55fa0c42b 🐛(backend) fix info panel crash for unregistered rooms
The info panel was crashing when opening a room that was not
registered in the database (with ALLOW_UNREGISTERED_ROOMS=true),
because the API response did not include the room slug.

Instead of adding frontend fallbacks, update the unregistered-room
response to include the slug, keeping the API contract consistent
with registered rooms.

Note: this still relies on the unregistered-room response staying
aligned with the registered-room schema. Any future divergence
between the two responses could introduce similar issues.
A refactoring on the backend side is needed.

It closes #1441.

When the setting is disabled, only anonymous users can set a display
name freely; authenticated users always use their SSO display name.

Florent Chehab 7fa172d100 (visio) use compatible with summary v2
This commit introduces the compatibility with summary v2.
It tecnically doesn't break the compatibility with v1 as
v1 params are still sent. But we advise people using the
transcribe feature in their own deployments to adapt to the
new v2 API, as this compatibility will be removed in a
future major version.

* RecordingStatusChoices now has
EXTERNAL_PROCESS_SUCCESSFUL
& EXTERNAL_PROCESS_FAILED
Values, which are changed by a new webhook that
can be called by the transcribe service.
This webhook is protected by its own bearer token.
* Title for the document is computed in visio,
* Tests are added / updated accordingly

leo aee1847303 (backend) add LiveKit egress_ended fallback for saving recordings
Recording lifecycle previously relied exclusively on the MinIO storage-hook
endpoint to transition from STOPPED to SAVED, which made the system dependent
on MinIO bucket notifications and lifecycle configuration. Introduce support
for LiveKit egress_ended webhook (EGRESS_COMPLETE, EGRESS_LIMIT_REACHED) as
 an alternative finalization mechanism for self-hosted deployments that do
 not use MinIO / S3 hooks.

Change behavior of existing configuation RECORDING_STORAGE_EVENT_ENABLE.
When the LiveKit mechanism is enabled (RECORDING_STORAGE_EVENT_ENABLE=False),
RecordingEventsService.handle_complete is triggered from
LiveKitEventsService._handle_egress_ended.

Florent Chehab d13e3a8a5d ️(backend) change db state instead of using long running row lock
When analysing a file, the previous commit introduced a row level lock

This commit changes the locking mechanism so that it happens with
the upload state which avoids long running db locks and potential
perf issues.

Florent Chehab a82d7f885a 🔒️(backend) prevnt file change post checks
Before this commit, post a file check, the policy could be
reused to change the verified file.
Now, files are uplaoded to a temporary location, then inside
a transaction that prevents concurrent calls, the file is
copied to its final destination and the checks are run on that one.
A new file can still be updated with the policy but it will never be read, etc.

As part of this change, all files in the new tmp directory
on s3 should have an expiration policy.

lebaudantoine 7390673bfc ️(frontend) backport phone number formatting to the backend
Use the Python port of Google's phone number library on the backend
instead of the JS one on the client. Saves 140Kb of unnecessary JS
and avoids a complex dynamic import that would have been required to
optimize loading.

The transformation is static: the phone number lives in the Django
settings, so the backend can format it once and pass the result to
the client. This avoids every client loading the 140Kb library and
re-computing the same information.

Moreover, within a single client, the transformation was previously
re-computed several times during a webapp lifecycle.

lebaudantoine 385da86759 🔒️(backend) verify participant presence before mute operations
Ensure the participant requesting a mute action is still present
in the room before processing the request.

This mitigates scenarios where a previously issued token could be
reused after the meeting has ended.

Current token lifetime is intentionally long-lived and will be
refactored in the future to better align with LiveKit session
constraints. In the meantime, add this extra validation step to
reduce the attack surface.

lebaudantoine 32fbedd358 (backend) extend live synchronization to lobby access level updates
Extend the existing live synchronization mechanism beyond room
configuration to also include lobby access level changes.

This ensures that all owners and admins sharing a room maintain a

lebaudantoine 534cf000b2 (backend) expose room configuration to all API consumers
Update room serialization to include room configuration for all
users fetching the API response, not only room owners.
This behavior was inherited from the original upstream project.

At the moment, exposing this configuration does not appear to
introduce meaningful security concerns or provide attackers with
additional capabilities.

The decision will continue to be reviewed from a security
perspective, but sharing the configuration improves frontend
consistency and synchronization.

lebaudantoine 5a7a0da923 (backend) add synchronization mechanism for room configuration updates
Introduce synchronization of room configuration changes across
active participants.

When a room configuration is updated through a PUT operation, the
backend now performs an additional LiveKit API call to notify room
participants through a room metadata update event.

This ensures admins and owners quickly see up-to-date settings in
their administration panel. It also prepares the frontend for
automatic updates of unprivileged participants room’s data without
refetching it from the API.

An event-driven design was chosen instead of storing the full room
configuration in LiveKit metadata. While embedding the state
directly in metadata would provide immediate synchronization, it
would also require initializing and maintaining configuration
state during room creation or webhook handling, increasing the
risk of operational failures and regressions.

Instead, the backend emits lightweight synchronization events and
active clients update their React Query cache, which remains the
single source of truth for room configuration data.

EpsilonFO a2bccf4f4f 🐛(backend) make start-recording atomic and fault-tolerant
Wrap Recording and RecordingAccess creation in a single transaction so a
partial failure does not leave orphan rows, and return 409 instead of 500

2026-04-29 20:32:25 +02:00
lebaudantoine ecb710688d (backend) introduce add-ons authentication backend
Add a new authentication backend for add-ons, with a core service
managing session state in cache and exposing three API endpoints.

Microsoft Add-ins recommend launching authentication from the
side panel via a dialog, then returning the JWT to the parent
context using postMessage. However, due to Django and SSO security
constraints (window.opener not preserved), this approach is not
viable.

Implement a three-step authentication flow:

- `/init`: create a session, return a short-lived transit token
  and CSRF token. Store session ID in a secure HttpOnly cookie.
- `/poll`: allow the add-on to poll until authentication is
  complete, then consume the session and clear the cookie.
- `/exchange`: exchange the transit token for a JWT, which is
  later retrieved via the `/poll` endpoint.

The add-on opens an authentication dialog, stores the transit
token in sessionStorage, and performs the exchange after login.

This approach works within iframe constraints and provides a
sufficiently secure v0 despite known limitations.

lebaudantoine d19023a1ba 🐛(backend) refactor lobby throttling to use participant id instead of IP
use the lobby participant cookie ID as the throttle cache key
rather than the client IP address.

This avoids penalising multiple users behind the same NAT or proxy
and aligns throttling with how LobbyService identifies participants.

This bug was spotted in production where users from ministries behind
NAT was blocked by throttling while using visio.

If no cookie is present yet, skip throttling for the request. The
cookie will be set on the first response and throttling will apply
from subsequent requests.

This throttle is intended to protect against accidental hammering
from buggy clients, not as a security control against DoS attacks.

This is not a security measure, we should use a WAF.
