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.

Affected configurations

• mattermost mattermost server (>= 9.5.0 < 9.5.7) • mattermost mattermost server 9.9.0
