• CVE-2026-94618: 0.19% estimated exploitation activity in the next 30 days; percentile 8.64 (FIRST EPSS, 2026-11-10). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary `GET /batchdownload` streams a batch ZIP to any requester who supplies its `uniqid`, without checking that the current user/session created it. In deployments where users have separate home directories, a valid low-privileged user who obtains an active archive id can download another user's batch archive, disclosing files the per-user boundary otherwise protects. Reported with explicit preconditions and bounded impact — not a universal "any user steals any file" issue.

Details The archive id is generated with plain `uniqid()` and no ownership metadata is bound to it before streaming. - `backend/Services/Archiver/Adapters/ZipArchiver.php:44` — `createArchive()` uses plain `uniqid()`. - `backend/Controllers/DownloadController.php:144-145` — `batchDownloadStart()` reads the tmpfs file by the request-supplied `uniqid` after only a charset `preg_replace()`. - `backend/Controllers/DownloadController.php:158` — the tmpfs archive is removed only after streaming. -…

# Patch Next advisory brief: CVE-2026-94618

Advisory: FileGator: Missing authorization in GET /batchdownload allows cross-user retrieval of another user's archive
IDs: CVE-2026-94618, GHSA-f74m-x83r-c4v4
Record: https://patchnext.com/advisories/cve-2026-94618 (revision 2, source checked 10 Nov 2026, 06:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: filegator/filegator 7.15.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist filegator/filegator: affected < 7.15.0; fixed in 7.15.0

## Suggested inspection (read-only)
- Packagist filegator/filegator: 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 filegator/filegator.
- 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.
