Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

Description
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
- Deploy AVideo using
docker compose up -d - Send:
curl http://target/.env - The full
.envfile 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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wwbn/avideo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update wwbn/avideo to 29.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-33692 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
