Vulnerability in admidio/admidio (CVE-2026-47226)

Summary

Vulnerability in admidio/admidio (CVE-2026-47226). Data can be tampered with by attackers. Exploitable via folder_uuid. Mitigation: upgrade to 5.0.7 or later.

Original description

The description as published by the source.

Summary

An authenticated Admidio member with upload rights on any one folder can permanently delete files from folders where they have only view access. The authorization check at the top of modules/documents-files.php evaluates upload rights against the attacker-supplied folder_uuid URL parameter — not the file's actual parent folder. The file_delete handler then only verifies view rights on the file's real location, never upload rights. By passing a folder they legitimately own in folder_uuid while targeting a file in a restricted folder via file_uuid, an attacker bypasses the upload-right check entirely and permanently deletes the file.

This is an incomplete fix of GHSA-rmpj-3x5m-9m5f, which was patched in v5.0.7 but remains exploitable in v5.0.9.

Affected Version: Admidio v5.0.9


Details

Root Cause File: modules/documents-files.php

Issue 1 — folder_uuid is not required for file_delete mode (line 67):

$getFolderUUID = admFuncVariableIsValid($_GET, 'folder_uuid', 'uuid', array(
    'requireValue' => !in_array($getMode, array('list', 'file_delete', 'download'))
));

Issue 2 — The top-level upload-right check loads the folder from the attacker-controlled URL parameter, not the file's actual parent folder (lines 79–88):

if ($getMode != 'list' && $getMode != 'download') {
    $folder = new Folder($gDb);
    $folder->getFold…

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify
    grep -r 'admidio/admidio' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で admidio/admidio を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch
    Upgrade admidio/admidio to 5.0.7

    ステージング環境で 5.0.7 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
