    Synapse 1.41.1 (2021-08-31)

    ⚡️ Due to the two security issues highlighted below, server administrators are encouraged to update Synapse. We are not aware of these vulnerabilities being exploited in the wild.

    🔒 Security advisory

    🛠 The following issues are fixed in v1.41.1.

    If an unauthorized user both knows the Room ID of a private room and that room's history visibility is set to shared, then they may be able to enumerate the room's members, including their display names.

    The unauthorized user must be on the same homeserver as a user who is a member of the target room.

    Fixed by 52c7a51cf.

    If an unauthorized user knows the Room ID of a private room, then its name, avatar, topic, and number of members may be disclosed through Group / Community features.

    The unauthorized user must be on the same homeserver as a user who is a member of the target room, and their homeserver must allow non-administrators to create groups (enable_group_creation in the Synapse configuration; off by default).

    Fixed by cb35df940a, #10723.

    🛠 Bugfixes

    • 🛠 Fix a regression introduced in Synapse 1.41 which broke email transmission on systems using older versions of the Twisted library. (#10713)

    Synapse 1.41.0 (2021-08-24)

    ✂ This release adds support for Debian 12 (Bookworm), but removes support for Ubuntu 20.10 (Groovy Gorilla), which reached End of Life last month.

    ⬆️ Note that when using workers the /_synapse/admin/v1/users/{userId}/media must now be handled by media workers. See the upgrade notes for more information.

    🔋 Features

    • 0️⃣ Enable room capabilities (MSC3244) by default and set room version 8 as the preferred room version when creating restricted rooms. (#10571)

    • Revert behaviour introduced in v1.38.0 that strips org.matrix.msc2732.device_unused_fallback_key_types from /sync when its value is empty. This field should instead always be present according to MSC2732. (#10623)
