{"id":"CVE-2026-33304","summary":"OpenEMR has Authorization Bypass in Dated Reminders Log","details":"OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, an authorization bypass in the dated reminders log allows any authenticated non-admin user to view reminder messages belonging to other users, including associated patient names and free-text message content, by crafting a GET request with arbitrary user IDs in the `sentTo[]` or `sentBy[]` parameters. Version 8.0.0.2 fixes the issue.","aliases":["GHSA-66j9-ffq4-h222"],"modified":"2026-04-10T05:42:41.702925Z","published":"2026-03-19T20:27:00.840Z","database_specific":{"cwe_ids":["CWE-639","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33304.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33304.json"},{"type":"ADVISORY","url":"https://github.com/openemr/openemr/security/advisories/GHSA-66j9-ffq4-h222"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33304"},{"type":"FIX","url":"https://github.com/openemr/openemr/commit/21dee7658a5f3b18c5750e3fae7324e875c1703a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openemr/openemr","events":[{"introduced":"0"},{"fixed":"d7ddb2dcb11332944c1e193ae0ac32eabe439f7c"}]}],"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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33304.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:N/A:N"}]}
