CVE-2026-33692

WWBN AVideo is an open source video platform. Versions prior to 29.0 expose .env files to unauthenticated users through the official Docker compose configuration. The official docker-compose.yml mounts the entire project root directory as the Apache document root, causing the .env file — which contains database credentials, admin passwords, and infrastructure configuration — to be served as a static file at /.env. No .htaccess rule or Apache configuration blocks access to dotfiles. Exploitation enables direct database access, admin panel takeover, and further lateral movement within the Docker network. This issue has been resolved in version 29.0.

This issue has been resolved in version 29.0.

Vulnerability Details

CWE: CWE-538 - Insertion of Sensitive Information into Externally-Accessible File or Directory

The official docker-compose.yml (line 61) mounts the entire project root directory as the Apache document root:

volumes:
  - "./:/var/www/html/AVideo"

This causes the .env file — which contains database credentials, admin passwords, and infrastructure configuration — to be served as a static file at /.env. No .htaccess rule or Apache configuration blocks access to dotfiles.

Exposed Information

An unauthenticated request to GET /.env returns:

DB_MYSQL_HOST=database
DB_MYSQL_USER=avideo
DB_MYSQL_PASSWORD=avideo
SYSTEM_ADMIN_PASSWORD=admin123
TLS_CERTIFICATE_FILE=/etc/apache2/ssl/localhost.crt
TLS_CERTIFICATE_KEY=/etc/apache2/ssl/localhost.key
NETWORK_SUBNET=172.30.0.0/16

Steps to Reproduce

Prerequisites

• AVideo deployed using the official docker-compose.yml
• No modifications to the default configuration

Steps

1. Deploy AVideo using docker compose up -d
2. Send: curl http://target/.env
3. The full .env file contents are returned, including database credentials and admin password

Impact

• Attacker: Unauthenticated (any remote user)
• Victim: AVideo server and database
• Specific damage: Attacker obtains database credentials (DB_MYSQL_USER, DB_MYSQL_PASSWORD), admin password (SYSTEM_ADMIN_PASSWORD), and internal network topology (NETWORK_SUBNET). This enables direct database access, admin panel takeover, and further lateral movement within the Docker network.

Proposed Fix

Add a .htaccess rule to block access to dotfiles:

# Block access to hidden files (.env, .git, etc.)
<FilesMatch "^\.">
    Order Allow,Deny
    Deny from all
</FilesMatch>

Or configure Apache to deny dotfile access in the virtual host configuration.
