CVE-2017-18107
Various resources in the Crowd Demo application of Atlassian Crowd before version 3.1.1 allow remote attackers to modify add, modify and delete users & groups via a Cross-site request forgery (CSRF) vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.
