Details
As written in the advisory (Markdown source, shown as plain text).
When running in a High Availability configuration, Mattermost fails to sanitize some of the `user_updated` and` post_deleted` events broadcast to all users, leading to disclosure of sensitive information to some of the users with currently connected Websocket clients.
