CVE-2026-33934
March 25, 2026
OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0.3 have a missing authorization check in "portal/sign/lib/show-signature.php" that allows any authenticated patient portal user to retrieve the drawn signature image of any staff member by supplying an arbitrary "user" value in the POST body. The companion write endpoint ("save-signature.php") was already hardened against this same issue, but the read endpoint was not updated to match. Version 8.0.0.3 patches the issue.
