Howdy All,
We wanted to reach out on this suggestion to re-iterate the official Atlassian recommendations to mitigate the risks of CVE-2019-3395/6.
Upgrade Confluence to an unaffected version
Atlassian has released a fix for these vulnerabilities and has backported these fixes to several versions. Download and upgrade to one of the following versions of Confluence:
Temporary workaround
If you are unable to upgrade Confluence immediately, then as a temporary workaround disable the affected system plugins:
We understand that disabling the WebDAV and Widget Connector plugins can be disruptive but it is only recommended as a temporary measure until an upgrade to an unaffected version can be performed.
If you have any issues with upgrading Confluence or implementing the workaround, any questions about the vulnerabilities, or any concerns please contact Atlassian Support.
