{"id":"CVE-2026-103939","published":"2026-11-05T20:17:38.510","lastModified":"2026-11-05T21:18:34.773","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.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openemr/openemr/commit/f760adc7bddaf9d118e1a0d40590e686783ed21b","tags":[]},{"url":"https://github.com/openemr/openemr/pull/13197","tags":[]},{"url":"https://github.com/openemr/openemr/releases/tag/v8_3_0","tags":[]},{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-xhv3-qr55-56h3","tags":[]},{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-xhv3-qr55-56h3","tags":[]}],"exploitRefs":[{"url":"https://github.com/openemr/openemr/commit/f760adc7bddaf9d118e1a0d40590e686783ed21b","tags":[]},{"url":"https://github.com/openemr/openemr/pull/13197","tags":[]},{"url":"https://github.com/openemr/openemr/releases/tag/v8_3_0","tags":[]},{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-xhv3-qr55-56h3","tags":[]},{"url":"https://github.com/openemr/openemr/security/advisories/GHSA-xhv3-qr55-56h3","tags":[]}],"hasPoc":true,"ai":null}
