CVE-2026-33038Public exploitNetwork attack vector

Unauthenticated takeover via exposed web installer

Published Mar 20, 2026 · Updated Mar 20, 2026

Missing authentication in AVideo before 26.0 allows remote attackers to take over uninitialized deployments through its web installer. The install/checkConfiguration.php endpoint accepts unauthenticated POST input to create the database and administrator account and write videos/configuration.php with attacker-controlled values. Exploitation requires videos/configuration.php to be absent, after which the attacker gains full administrative control and can read or alter application data.
