{"id":"CVE-2026-34055","state":"PUBLISHED","title":"OpenEMR has IDOR in Patient Notes Web UI allows unauthorized note access/modification","description":"OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the legacy patient notes functions in `library/pnotes.inc.php` perform updates and deletes using `WHERE id = ?` without verifying that the note belongs to a patient the user is authorized to access. Multiple web UI callers pass user-controlled note IDs directly to these functions. This is the same class of vulnerability as CVE-2026-25745 (REST API IDOR), but affects the web UI code paths. Version 8.0.0.3 patches the issue.","publishedAt":"2026-03-25T23:49:06.009Z","updatedAt":"2026-03-26T14:22:43.312Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["openemr openemr"],"affected":[{"vendor":"openemr","product":"openemr","versions":[{"version":"< 8.0.0.3","status":"affected"}]}],"references":["https://github.com/openemr/openemr/security/advisories/GHSA-8gj5-r8vm-mghq","https://github.com/openemr/openemr/commit/214c9b4585a6f1c8c22750172d47f0e258fec0bf","https://github.com/openemr/openemr/releases/tag/v8_0_0_3"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/34xxx/CVE-2026-34055.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-34055","state":"PUBLISHED","datePublished":"2026-03-25T23:49:06.009Z","dateUpdated":"2026-03-26T14:22:43.312Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-25T15:29:04.746Z"},"containers":{"cna":{"title":"OpenEMR has IDOR in Patient Notes Web UI allows unauthorized note access/modification","descriptions":[{"lang":"en","value":"OpenEMR is a free and open source electronic health records and medical practice management application.
