{"id":"CVE-2026-27943","summary":"OpenEMR's Eye Exam View Trusts form_id Without Verifying Patient/Encounter Ownership","details":"OpenEMR is a free and open source electronic health records and medical practice management application. In versions up to and including 8.0.0, the eye exam (eye_mag) view loads data by `form_id` (or equivalent) without verifying that the form belongs to the current user’s patient/encounter context. An authenticated user can access or edit any patient’s eye exam by supplying another form ID; in some flows the session’s active patient may also be switched. A fix is available on the `main` branch of the OpenEMR GitHub repository.","aliases":["GHSA-q96x-qw99-6xq9"],"modified":"2026-08-12T03:51:11.391336614Z","published":"2026-02-26T01:30:31.363Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27943.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27943.json"},{"type":"ADVISORY","url":"https://github.com/openemr/openemr/security/advisories/GHSA-q96x-qw99-6xq9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27943"},{"type":"FIX","url":"https://github.com/openemr/openemr/commit/c87489bf63f2701b634d948279e104f2ed3df1c0"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openemr/openemr","events":[{"introduced":"0"},{"fixed":"c87489bf63f2701b634d948279e104f2ed3df1c0"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"8.0.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:open-emr:openemr:*:*:*:*:*:*:*:*"}}],"versions":["v3_0_1","v3_0_0","v2_9_0","v2_8_3","v2_8_2","v2_8_1","v2_8_0","v2_7_3-rc1","v2_7_2","v2_7_2-rc2","v2_7_2-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27943.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
