CVE-2022-26134

What the flaw is

Atlassian Confluence Server and Data Center contain a remote code execution vulnerability that allows for an unauthenticated attacker to perform remote code execution.

Description as published by CISA. We have not independently reproduced it.

What CISA requires

Immediately block all internet traffic to and from affected products AND apply the update per vendor instructions [https://confluence.atlassian.com/doc/confluence-security-advisory-2022-06-02-1130377146.html] OR remove the affected products by the due date on the right. Note: Once the update is successfully deployed, agencies can reassess the internet blocking rules.

This deadline is binding on US federal civilian agencies under BOD 22-01. It is not a legal deadline for anyone else, but it is a useful urgency signal — CISA sets it by how actively the flaw is being used, not by CVSS.

Public exploit code

289 public repositories referencing this CVE have been catalogued on GitHub. That volume usually means a reliable, widely-reproduced exploit. Treat this as a strong signal to prioritise patching, not as a verified working exploit — many such repositories are scanners, write-ups or forks rather than functional code.
