• CVE-2026-47230: 0.30% estimated exploitation activity in the next 30 days; percentile 22.72 (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 mode filerenamesave shares the same root-cause shape as the cross-folder move bug (05-documents-cross-folder-move-idor.md): the top-level rights check at lines 79-89 validates hasUploadRight() on the URL parameter folderuuid, but the rename operation acts on fileuuid — a separate URL parameter — without re-checking the folder that actually contains the file. DocumentsService::renameFile() resolves the target file via getFileForDownload() (which permits view-readable files) but does not require upload right on the file's source folder. Result: a user with upload right on any folder A can rename a file in folder B as long as they can view it. They can also overwrite the file's description. Details Vulnerable Code modules/documents-files.php:79-89 — top-level check binds to URL folderuuid: src/Documents/Service/DocumentsService.php:272-315 — renameFile() resolves the file via getFileForDownload() (view-only) and never re-verifies upload right on the…

# Patch Next advisory brief: CVE-2026-47230

Advisory: Admidio: IDOR in documents-files.php allows cross-folder file rename and description changes by unauthorized uploaders
IDs: CVE-2026-47230, GHSA-q6w3-hpfv-rg36
Record: https://patchnext.com/advisories/cve-2026-47230 (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: Medium (CVSS 6.5)
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-q6w3-hpfv-rg36 (GitHub-reviewed advisory GHSA-q6w3-hpfv-rg36 lists affected ranges: Packagist admidio/admidio >=0 <=5.0.9)
