Affected versions of Atlassian Confluence Server and Data Center allowed remote attackers with system administration permissions to bypass velocity template injection mitigations via an injection vulnerability in custom user macros.
Does this matter?
Lower severity and a low EPSS score (1.52%). Track it; it rarely justifies an emergency change on its own.
