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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openemr/openemr/commit/7973cab3fe3f2fd2374ed71c02605e3c93491c36","tags":[]},{"url":"https://github.com/openemr/openemr/pull/13200","tags":[]},{"url":"https://github.com/openemr/openemr/releases/tag/v8_3_0","tags":[]},{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-r3q3-p493-95x8","tags":[]}],"exploitRefs":[{"url":"https://github.com/openemr/openemr/commit/7973cab3fe3f2fd2374ed71c02605e3c93491c36","tags":[]},{"url":"https://github.com/openemr/openemr/pull/13200","tags":[]},{"url":"https://github.com/openemr/openemr/releases/tag/v8_3_0","tags":[]},{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-r3q3-p493-95x8","tags":[]}],"hasPoc":true,"ai":null}
