Mattermost is vulnerable to Information Disclosure. The vulnerability is due to a failure to check whether the Allow users to view archived channels
setting is enabled during permalink previews display. This flaw allows members to view permalink previews of archived channels, even if the Allow users to view archived channels
setting is disabled. As a result an attacker could exploit this issue to view permalink previews of archived channels.
