Admidio is an open-source user management solution. From version 5.0.0 to before version 5.0.8, Admidio relies on adm_my_files/.htaccess to deny direct HTTP access to uploaded documents. The Docker image ships with AllowOverride None in the Apache configuration, which causes Apache to silently ignore all .htaccess files. As a result, any file uploaded to the documents module regardless of the role-based permissions configured in the UI, is directly accessible over HTTP without authentication by anyone who knows the file path. The file path is disclosed in the upload response JSON. This issue has been patched in version 5.0.8.

GHSA-7fh7-8xqm-3g88 — Admidio allows Unauthenticated Access to Role-Restricted documents via neutralized .htaccess

Affected: Packagist: admidio/admidio

### Summary

Admidio relies on `adm_my_files/.htaccess` to deny direct HTTP access to uploaded documents. The Docker image ships with `AllowOverride None` in the Apache configuration, which causes Apache to silently ignore all `.htaccess` files. As a result, any file uploaded to the documents module regardless of the _role-based_ permissions configured in the UI, is directly accessible over HTTP without authentication by anyone who knows the file path. The file path is disclosed in the upload response JSON.

### Root Cause

**File 1: Intended protection (ignored):** `adm_my_files/.htaccess` ```apache Require all denied ``` <img width="408" height="403" alt="imagen" src="https://github.com/user-attachments/assets/95f0d389-a1a9-4dc4-9840-7f189d2c58ff" />

**File 2: Apache config that neutralizes it:**

* Command in order to search in Docker container: `docker exec admidio-sec-app cat /etc/apache2/apache2.conf`

`/etc/apache2/apache2.conf` (Docker image) ```apache <Directory ${APACHE_DOCUMENT_ROOT}> AllowOverride None </Directory> ```

`AllowOverride None` instructs Apache to skip `.htaccess` processing entirely, the deny rule never executes. The upload directory is inside the web root at `/opt/app-root/src/adm_my_files/` and returns **HTTP 200** for direct requests.

**File 3: Upload response leaks the direct URL:** `system/file_up…
