CVE-2026-103939 Details

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.
