Advisory GHSA-w6xh-c82w-h997 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/v2
github.com/mattermost/mattermost/server/v8

Description:
Mattermost versions 10.2.x <= 10.2.0, 9.11.x <= 9.11.5, 10.0.x <= 10.0.3, 10.1.x <= 10.1.3 fail to properly handle posts with attachments containing fields that cannot be cast to a String, which allows an attacker to cause the webapp to crash via creating and sending such a post to a channel.
