CVE-2019-20098: Atlassian Jira Data Center

Medium severity, CVSS 4.3. EPSS: 0.8% chance of exploitation in the next 30 days.

The VerifySmtpServerConnection!add.jspa component in Atlassian Jira Server and Data Center before version 8.7.0 is vulnerable to cross-site request forgery (CSRF). An attacker could exploit this by tricking an administrative user into making malicious HTTP requests, allowing the attacker to enumerate hosts and open ports on the internal network where Jira server is present.
