CVE-2026-33038: Wwbn Avideo

High severity, CVSS 8.1. EPSS: 0.5% chance of exploitation in the next 30 days.

WWBN AVideo is an open source video platform. Versions 25.0 and below are vulnerable to unauthenticated application takeover through the install/checkConfiguration.php endpoint. install/checkConfiguration.php performs full application initialization: database setup, admin account creation, and configuration file write, all from an unauthenticated POST input. The only guard is checking whether videos/configuration.php already exists. On uninitialized deployments, any remote attacker can complete the installation with attacker-controlled credentials and an attacker-controlled database, gaining full administrative access. This issue has been fixed in version 26.0.

Affected products

• Wwbn Avideo: before 26.0 (fixed in 26.0)
