Security advisory

The following issues are fixed in 1.85.0 (and RCs).

  • GHSA-26c5-ppr8-f33p / CVE-2023-32682 — Low Severity

    It may be possible for a deactivated user to login when using uncommon configurations.

  • GHSA-98px-6486-j7qc / CVE-2023-32683 — Low Severity

    A discovered oEmbed or image URL can bypass the url_preview_url_blacklist setting potentially allowing server side request forgery or bypassing network policies. Impact is limited to IP addresses allowed by the url_preview_ip_range_blacklist setting (by default this only allows public IPs).

Synapse 1.84.0 (2023-05-23)

The worker_replication_* configuration settings have been deprecated in favour of configuring the main process consistently with other instances in the instance_map. The deprecated settings will be removed in Synapse v1.88.0, but changing your configuration in advance is recommended. See the upgrade notes for more information.

Synapse 1.81.0 (2023-04-11)

Synapse now attempts the versioned appservice paths before falling back to the legacy paths. Usage of the legacy routes should be considered deprecated.

Additionally, Synapse has supported sending the application service access token via the Authorization header since v1.70.0. For backwards compatibility it is also sent as the access_token query parameter. This is insecure and should be considered deprecated.

A future version of Synapse (v1.88.0 or later) will remove support for legacy application service routes and query parameter authorization.

Synapse 1.76.0 (2023-01-31)

The 1.76 release is the first to enable faster joins (MSC3706 and MSC3902) by default. Admins can opt-out: see the upgrade notes for more details.

The upgrade from 1.75 to 1.76 changes the account data replication streams in a backwards-incompatible manner. Server operators running a multi-worker deployment should consult the upgrade notes.

Those who are poetry installing from source using our lockfile should ensure their poetry version is 1.3.2 or higher; see upgrade notes.

Notes on faster joins

The faster joins project sees the most benefit when joining a room with a large number of members (joined or historical). We expect it to be particularly useful for joining large public rooms like the Matrix HQ or Synapse Admins rooms.

After a faster join, Synapse considers that room "partially joined". In this state, you should be able to

  • read incoming messages;
  • see incoming state changes, e.g. room topic changes; and
  • send messages, if the room is unencrypted.

Synapse has to spend more effort to complete the join in the background. Once this finishes, you will be able to

  • send messages, if the room is in encrypted;
  • retrieve room history from before your join, if permitted by the room settings; and
  • access the full list of room members.

Improved Documentation

  • Describe the ideas and the internal machinery behind faster joins. (#14677)

Synapse 1.76.0rc2 (2023-01-27)

Bugfixes

  • Faster joins: Fix a bug introduced in Synapse 1.69 where device list EDUs could fail to be handled after a restart when a faster join sync is in progress. (#14914)

Internal Changes

Synapse 1.76.0rc1 (2023-01-25)

Features

  • Faster joins: always serve a partial join response to servers that request it with the stable query param. (#14839)
  • Faster joins: allow non-lazy-loading ("eager") syncs to complete after a partial join by omitting partial state rooms until they become fully stated. (#14870)
