CVE-2026-105667 Details
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.
A vulnerability exists in J4Care dcm4che's HL7 listener, which by default accepts ADT^A40 patient-merge messages without authenticating the sending application. This allows a remote sender to reassign studies and related workflow records between patient identities. Notably, the archive's unmerge function does not reverse this action.
J4Care has released a patch for this vulnerability. Users are advised to update to version 5.35.2 or later.
