Advisory GHSA-q22q-2rrf-m27p 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 and 9.8.x <= 9.8.1 fail to disallow unsolicited invites to expose access to local channels, when shared channels are enabled, which allows a malicious remote to send an invite with the ID of an existing local channel, and that local channel will then become shared without the consent of the local admin.
