Attackers can supply a traversal sequence in the db parameter to resolve outside the intended temporary directory, and by chaining this with an open redirect in dicom_frame.php, an unauthenticated attacker can deliver a crafted URL that triggers arbitrary recursive directory deletion within an authenticated Superuser's session.","published":"2026-08-17T21:16:44.930","modified":"2026-08-17T21:16:44.930","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/openemr/openemr/commit/2d8a69f0f343c8e8c6ee1b42d224c24a7a4ba415","label":"openemr/openemr@2d8a69f"},"references":[{"type":"WEB","url":"https://github.com/openemr/openemr/commit/2d8a69f0f343c8e8c6ee1b42d224c24a7a4ba415"},{"type":"WEB","url":"https://github.com/openemr/openemr/pull/11951"},{"type":"WEB","url":"https://github.com/openemr/openemr/releases/tag/v8_2_0"},{"type":"WEB","url":"https://github.com/openemr/openemr/security/advisories/GHSA-hj9x-33vw-5g3x"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openemr-path-traversal-arbitrary-directory-deletion-via-standard-tables-manage-php"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T21:16:44.930"}}
