Overview
edu.internet2.middleware.grouper:grouper is an Internet2 Groups Management Toolkit
Affected versions of this package are vulnerable to Incorrect Authorization via improper job scheduling in the loader jobs configuration process. A group administrator who is not a member of the Grouper wheel (sysadmin) group can exploit this vulnerability by creating a loader job on a group they manage. Although the job is not scheduled immediately, it will be scheduled the next time the daemon container restarts or when a privileged user triggers Daemon actions → Schedule jobs, allowing the non-sysadmin to execute unauthorized loader jobs.
