CVE-2017-18036
The Github repository importer in Atlassian Bitbucket Server before version 5.3.0 allows remote attackers to determine if a service they could not otherwise reach has open ports via a Server Side Request Forgery (SSRF) vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.
