For OpenNMS Meridian versions meridian-foundation-2015.1.0-1 through meridian-foundation-2019.1.18-1, update to a version that includes the fix for this issue. For OpenNMS Meridian versions meridian-foundation-2020.1.0-1 through meridian-foundation-2020.1.6-1, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the /opennms/admin/userGroupView/users/updateUser API endpoint to minimize the risk of exploitation.
