CWE-284

Description

Mattermost versions 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2 and 9.5.x <= 9.5.5 fail to prevent users from specifying a RemoteId for their posts which allows an attacker to specify both a remoteId and the post ID, resulting in creating a post with a user-defined post ID. This can cause some broken functionality in the channel or thread with user-defined posts

Affected configurations

• mattermost mattermost (>= 9.5.0 < 9.5.6) • mattermost mattermost (>= 9.6.0 < 9.6.3) • mattermost mattermost (>= 9.7.0 < 9.7.4) • mattermost mattermost (>= 9.8.0 < 9.8.1)
