Hey Priyanka!

So, regarding the CVE-2022-26138: it affects Confluence Server and Data Center instances that have ever installed and enabled vulnerable versions of the Questions for Confluence app.

Vulnerable versions can be found below:

Questions for Confluence 2.7.x	2.7.34 2.7.35
Questions for Confluence 3.0.x	3.0.2

Warning: It's possible for an instance to have previously installed then uninstalled the app, and still be affected.

How to determine if you are affected:

A Confluence Server or Data Center instance is affected if it has an active user account with the following information:

• User: disabledsystemuser

• Username: disabledsystemuser

• Email: dontdeletethisuser@email.com

 It is possible for this account to be present if the Questions for Confluence app has previously been installed and uninstalled.

If this account does not show up in the list of active users, the Confluence instance is not affected.

You can find additional details on this CVE, how to check if your environment is affected and steps to remediate on this link.

You can find the FAQ for CVE-2022-26138 on this link.

Please let me know if I was able to properly clarify your question!

Best regards,

Murilo.

Hi @Priyanka Sharma . The problem is since 6.x is well beyond EOL (I am on 6.13.8), there is no information. Atlassian did not do any research or testing, and won't provide mitigation steps for an EOL release.

But this notice was specifically for Questions for Confluence app. So if you do not have Questions installed, you probably can ignore this alert.
