{"id":"CVE-2026-27943","state":"PUBLISHED","title":"OpenEMR's Eye Exam View Trusts form_id Without Verifying Patient/Encounter Ownership","description":"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.","publishedAt":"2026-02-26T01:30:31.363Z","updatedAt":"2026-02-26T15:28:13.472Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["openemr openemr"],"affected":[{"vendor":"openemr","product":"openemr","versions":[{"version":"<= 8.0.0","status":"affected"}]}],"references":["https://github.com/openemr/openemr/security/advisories/GHSA-q96x-qw99-6xq9","https://github.com/openemr/openemr/commit/c87489bf63f2701b634d948279e104f2ed3df1c0"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27943.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27943","state":"PUBLISHED","datePublished":"2026-02-26T01:30:31.363Z","dateUpdated":"2026-02-26T15:28:13.472Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-25T03:11:36.690Z"},"containers":{"cna":{"title":"OpenEMR's Eye Exam View Trusts form_id Without Verifying Patient/Encounter Ownership","descriptions":[{"lang":"en","value":"OpenEMR is a free and open source electronic health records and medical practice management application.
