{"id":"CVE-2026-47231","aliases":["GHSA-x628-457g-2pw9"],"url":"https://o3.security/vulnerability/CVE-2026-47231","summary":"Admidio has IDOR in `documents-files.php` `mode=move_save` that lets any folder-uploader exfiltrate files from private folders","details":"Admidio is an open-source user management solution. Prior to version 5.0.10, `modules/documents-files.php` gates state-changing modes by checking that the actor has `hasUploadRight()` on the URL parameter `folder_uuid`. The `move_save` handler then operates on a *separate* URL parameter `file_uuid` and calls `File::moveToFolder($destFolderUUID)`. `File::moveToFolder()` checks the upload right on the destination folder but never on the source folder containing the file. As a result, any user who can upload to any single folder can move any file from any other folder — including private folders to which they have no view rights — into a folder they control, and then download it. Confidentiality is broken (private file contents leak) and integrity is broken (the file is removed from the original location). Version 5.0.10 contains a fix.","published":"2026-08-12T13:17:16.419Z","modified":"2026-08-14T03:51:58.664959977Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":{"score":0.00212,"percentile":0.11839,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"admidio/admidio","fixedVersion":"5.0.10"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/security/advisories/GHSA-x628-457g-2pw9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47231.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47231"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T03:51:58.664959977Z"}}
