## Security advisory

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

- [GHSA-26c5-ppr8-f33p](GHSA-26c5-ppr8-f33p) / [CVE-2023-32682](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-32682) — Low Severity

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

- [GHSA-98px-6486-j7qc](GHSA-98px-6486-j7qc) / [CVE-2023-32683](https://cve.mitre.org/cgi-bin/cvename.cgi?name=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 1.84.1 (2023-05-26)
===========================

This patch release fixes a major issue with homeservers that do not have an `instance_map` defined but which do use workers.

Synapse 1.81.0 (2023-04-11)
===========================

Synapse now attempts the versioned appservice paths before falling back to the
[legacy paths](https://spec.matrix.org/v1.6/application-service-api/#legacy-routes).
Usage of the legacy routes should be considered deprecated.

Additionally, Synapse has supported sending the application service access token
via [the `Authorization` header](https://spec.matrix.org/v1.6/application-service-api/#authorization)
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.


No significant changes since 1.81.0rc2.
