Summary

OpenEMR before 8.3.0 is affected. The new_recall branch of interface/main/messages/save.php accepts a caller-supplied patient identifier without enforcing patient-level or recall-workflow authorization. A low-privilege authenticated remote attacker who knows or enumerates a patient identifier can read patient details, contact fields, HIPAA notification preferences, recent appointment information and existing recall information (CWE-284).
