Prior to 8.3.0, library/ajax/set_pt.php allows any authenticated user to set an arbitrary patient identifier in the active session without an ACL check, and interface/patient_file/download_template.php trusts that session value while enforcing only CSRF validation. A low-privilege user can select another patient and download a rendered document template containing the patient's demographics, encounter information, allergies, medications, and problem list despite lacking patients/docs access. This issue is fixed in version 8.3.0.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793908524266,"publishedAt":1793908524266,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/openemr/openemr/security/advisories/GHSA-r3q3-p493-95x8"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/pull/13200"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/commit/7973cab3fe3f2fd2374ed71c02605e3c93491c36"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/releases/tag/v8_3_0"}],"remediation":[],"revision":"e25c62794e731d13cb292b7c96e427943e3dfaa3a3e6930babf8be7d825d3ae2","sources":[{"modifiedAt":1793908524266,"name":"CNA: GitHub_M","retrievedAt":1793909549950,"url":"https://www.cve.org/CVERecord?id=CVE-2026-104139"}],"ssvc":null,"status":"published","title":"OpenEMR: Missing Authorization on Document Template Download Endpoint Allows Any Authenticated User to Read Another Patient's PHI","updatedAt":1793909549950}
