{"affected":[{"product":"openemr","source":"CNA: GitHub_M","vendor":"openemr","versions":[{"status":"affected","version":"< 8.3.0"}]}],"cveId":"CVE-2026-103939","cwes":["CWE-862"],"description":"OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/modules/custom_modules/oe-module-weno/scripts/file_download.php has no ACL or CSRF check and ignores the result of validateAdminCredentials(). When the Weno module is enabled, the default GET path calls PharmacyService::removeWenoPharmacies() before attempting a refetch, allowing any authenticated user to truncate the weno_pharmacy table and allowing a cross-site request to trigger the same operation through a logged-in victim. A failed later download can leave the e-prescribing pharmacy directory empty and unavailable. 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-xhv3-qr55-56h3"}],"kev":null,"metrics":[{"score":5.4,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","version":"3.1"}],"modifiedAt":1793912669778,"publishedAt":1793908957676,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/openemr/openemr/security/advisories/GHSA-xhv3-qr55-56h3"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/pull/13197"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openemr/openemr/commit/f760adc7bddaf9d118e1a0d40590e686783ed21b"},{"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-xhv3-qr55-56h3"}],"remediation":[],"revision":"4e76b8aeb0458637ee30d7a3312927e49fc333a21e8843b778d1ce797c7351c6","sources":[{"modifiedAt":1793912669778,"name":"CNA: GitHub_M","retrievedAt":1793913719730,"url":"https://www.cve.org/CVERecord?id=CVE-2026-103939"}],"ssvc":{"assessedAt":1793912648566,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"OpenEMR: Weno `file_download.php`: missing ACL/CSRF truncates the e-prescribing pharmacy directory","updatedAt":1793913719730}
