Auth bypass in Open-Emr Openemr
CVE-2026-25744
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, the encounter vitals API accepts an `id` in the request body and treats it as an UPDATE. There is no verification that the vital belongs to the current patient or encounter. An authenticated user with encounters/notes permission can overwrite any patient's vitals by supplying another patient's vital `id`, leading to medical record tampering. Version 8.0.0.2 fixes the issue.
