SCA: security update for matrix-synapse (GHSA-45cj-f97f-ggwv)

high Tenable Self-Hosted Container Security Plugin ID 409958

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. The
 Matrix Federation API allows remote homeservers to request the authorization events in a room. This is
 necessary so that a homeserver receiving some events can validate that those events are legitimate and
 permitted in their room. However, in versions of Synapse up to and including 1.68.0, a Synapse homeserver
 answering a query for authorization events does not sufficiently check that the requesting server should
 be able to access them. The issue was patched in Synapse 1.69.0. Homeserver administrators are advised to
 upgrade. (CVE-2022-39335)
