CVE-2026-33038: AVideo affected by unauthenticated application takeover via exposed web installer on uninitialized deployments

March 17, 2026 (updated March 20, 2026)

The install/checkConfiguration.php endpoint performs full application initialization — database setup, admin account creation, and configuration file write — from 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.
