EPSS

• CVE-2026-47231: 0.35% estimated exploitation activity in the next 30 days; percentile 28.66 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary modules/documents-files.php gates state-changing modes by checking that the actor has hasUploadRight() on the URL parameter folderuuid. The movesave handler then operates on a separate URL parameter fileuuid 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). Details Vulnerable Code modules/documents-files.php:79-89 — top-level rights check binds to URL folderuuid: modules/documents-files.php:187-204 — the movesave branch loads the file by UUID without revalidating the file's actual parent folder:…

# Patch Next advisory brief: CVE-2026-47231

Advisory: Admidio has IDOR in `documents-files.php` `mode=move_save` that lets any folder-uploader exfiltrate files from private folders
IDs: CVE-2026-47231, GHSA-x628-457g-2pw9
Record: https://patchnext.com/advisories/cve-2026-47231 (revision 1, source checked 26 Oct 2026, 14:48 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: admidio/admidio 5.0.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist admidio/admidio: affected <= 5.0.9; fixed in 5.0.10

## Suggested inspection (read-only)
- Packagist admidio/admidio: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on admidio/admidio.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-x628-457g-2pw9 (GitHub-reviewed advisory GHSA-x628-457g-2pw9 lists affected ranges: Packagist admidio/admidio >=0 <=5.0.9)
