CVE-2019-11580 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Atlassian Crowd and Crowd Data Center had the pdkinstall development plugin incorrectly enabled in release builds. Attackers who can send unauthenticated or authenticated requests to a Crowd or Crowd Data Center instance can exploit this vulnerability to install arbitrary plugins, which permits remote code execution on systems running a vulnerable version of Crowd or Crowd Data Center. CISA has confirmed active exploitation in the wild. EPSS estimates a 95.36% chance of exploitation in the next 30 days.
