Advisory GHSA-9fpw-c9x7-cv3j 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 and 9.5.x <= 9.5.6 fail to validate the source of sync messages and only allow the correct remote IDs, which allows a malicious remote to set arbitrary RemoteId values for synced users and therefore claim that a user was synced from another remote.
