Can you explain this vulnerability to me?

This vulnerability in Mattermost Confluence Plugin versions before 1.5.0 allows attackers to create a channel subscription via an API call without having proper access to the channel. The plugin fails to verify if the user has access rights to the channel when editing channel subscriptions.


How can this vulnerability impact me? :

An attacker could subscribe to channels they do not have access to, potentially leading to unauthorized information flow or notifications related to those channels. This could result in limited integrity issues but does not directly impact confidentiality or availability.
