  • CISA Known Exploited Vulnerabilities catalogcisa.gov
Upstream source description

In the default configuration, the HL7 listener accepts ADT^A40 patient-merge messages without authenticating the sending application. A remote sender can reassign studies and related workflow records from one patient identity to another. The archive's unmerge does not reverse this.
