SCA: security update for github.com/matrix-org/dendrite (GHSA-pfw4-xjgm-267c)

medium Tenable Self-Hosted Container Security Plugin ID 417493

Description

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

 - Dendrite is a Matrix homeserver written in Go. In affected versions events retrieved from a remote
 homeserver using the `/get_missing_events` path did not have their signatures verified correctly. This
 could potentially allow a remote homeserver to provide invalid/modified events to Dendrite via this
 endpoint. Note that this does not apply to events retrieved through other endpoints (e.g. `/event`,
 `/state`) as they have been correctly verified. Homeservers that have federation disabled are not
 vulnerable. The problem has been fixed in Dendrite 0.9.8. Users are advised to upgrade. There are no known
 workarounds for this issue. (CVE-2022-39200)
