Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-33037 impacting wwbn avideo. Evaluated with CVSS Base Score of 8.1 (HIGH).

Original NVD Description

Source: NIST NVD
WWBN AVideo is an open source video platform. In versions 25.0 and below, the official Docker deployment files (docker-compose.yml, env.example) ship with the admin password set to "password", which is automatically used to seed the admin account during installation, meaning any instance deployed without overriding SYSTEM_ADMIN_PASSWORD is immediately vulnerable to trivial administrative takeover. No compensating controls exist: there is no forced password change on first login, no complexity validation, no default-password detection, and the password is hashed with weak MD5. Full admin access enables user data exposure, content manipulation, and potential remote code execution via file uploads and plugin management. The same insecure-default pattern extends to database credentials (avideo/avideo), compounding the risk. Exploitation depends on operators failing to change the default, a condition likely met in quick-start, demo, and automated deployments. This issue has been fixed in version 26.0.
