{"id":"CVE-2026-34055","summary":"OpenEMR has IDOR in Patient Notes Web UI allows unauthorized note access/modification","details":"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.","aliases":["GHSA-8gj5-r8vm-mghq"],"modified":"2026-04-10T05:43:00.438879Z","published":"2026-03-25T23:49:06.009Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34055.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34055.json"},{"type":"FIX","url":"https://github.com/openemr/openemr/commit/214c9b4585a6f1c8c22750172d47f0e258fec0bf"},{"type":"WEB","url":"https://github.com/openemr/openemr/releases/tag/v8_0_0_3"},{"type":"ADVISORY","url":"https://github.com/openemr/openemr/security/advisories/GHSA-8gj5-r8vm-mghq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34055"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openemr/openemr","events":[{"introduced":"0"},{"fixed":"7c96c8eefe460d6fadbccbe93d0fa6bf819acd69"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"8.0.0.3"}]}}],"versions":["v2_7_2","v2_7_2-rc1","v2_7_2-rc2","v2_7_3-rc1","v2_8_0","v2_8_1","v2_8_2","v2_8_3","v2_9_0","v3_0_0","v3_0_1","v8_0_0","v8_0_0_1","v8_0_0_2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34055.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
