Is my (Atlassian) Data Center / Server system affected?
You should await advice from Atlassian on how to mitigate in your scenario or consult your own security team. If you run package scans on your system, you will likely find some Spring packages. Whether your system is vulnerable will likely depend on what version of Jira/Confluence/Bitbucket you’re running, and likely also what JVM version you’re running in your system. You should keep checking for important security updates of your Atlassian host systems. If you have questions about this, please refer to Atlassian support for assistance: https://support.atlassian.com/, or await their public security advisories: https://confluence.atlassian.com/security/articles-951406100.html and FAQ’s: https://confluence.atlassian.com/kb/atlassian-knowledge-base-179443510.html
