{"affected":[{"product":"openemr","source":"CNA: GitHub_M","vendor":"openemr","versions":[{"status":"affected","version":"< 8.3.0"}]}],"cveId":"CVE-2026-115573","cwes":["CWE-862"],"description":"OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/classes/Controller.class.php allows explicit controller.php dispatch to controllers missing from CONTROLLER_ACL_MAP, and checkControllerAcl() returns without enforcing any permission for those entries. A low-privilege authenticated user can invoke C_X12Partner::edit_action_process() to create or alter insurance-routing hosts and credentials, or invoke C_PatientFinder::find_action_process() to enumerate patient names, dates of birth, and identifiers. The shared fail-open dispatcher root cause also exposes other administrative controllers that were intended to be reached through ACL-gated Practice Settings routes. This issue is fixed in version 8.3.0.","epss":null,"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/openemr/openemr/security/advisories/GHSA-9rj4-fxmj-c4r7"}],"kev":null,"metrics":[{"score":8.1,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"}],"modifiedAt":1793912713087,"publishedAt":1793908866409,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/openemr/openemr/security/advisories/GHSA-9rj4-fxmj-c4r7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/pull/13565"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/commit/64f8491d850b2e22ed4fceb14fa67e27fef62cd1"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/releases/tag/v8_3_0"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/openemr/openemr/security/advisories/GHSA-9rj4-fxmj-c4r7"}],"remediation":[],"revision":"f61291b5eed750bb4695bd20585253ca1254666ee22197823a7c07bd9239a99d","sources":[{"modifiedAt":1793912713087,"name":"CNA: GitHub_M","retrievedAt":1793913749872,"url":"https://www.cve.org/CVERecord?id=CVE-2026-115573"}],"ssvc":{"assessedAt":1793912689686,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"OpenEMR: Broken Access Control in controller.php Enables Insurance Routing Credential Hijack and PHI Enumeration","updatedAt":1793913749872}
