Advisory GHSA-vg6q-84p8-qvqh references a vulnerability in the following Go modules:

Module
github.com/mattermost/mattermost-server
github.com/mattermost/mattermost-server/v5
github.com/mattermost/mattermost-server/v6
github.com/mattermost/mattermost/server/v8

Description:
Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to disallow users to set their own remote username, when shared channels were enabled, which allows a user on a remote to set their remote username prop to an arbitrary string, which would be then synced to the local server as long as the user hadn't been synced before.
