            There seems to be something "off" in the some parts of the tables above:

            Affected versions Fixed versions Problem
            8.9.0 8.9.0 8.9.0 can't be the affected version but at the same time the fixed version

            If it allows an unauthenticated attacker to expose assets in your environment susceptible to exploitation why does it have no impact to confidentiality, but has a high impact to availability? Should not it be exactly another way: high impact to confidentiality and no impact to availability?

            Is there any possibility to mitigate the risk through updating the dependency directly without a Confluence update if we are not able to update Confluence next days?
