CVE-2026-45731: AVideo: Authenticated Arbitrary File Read in view/update.php

May 18, 2026 (updated June 9, 2026)

view/update.php reads $_POST[‘updateFile’] as a relative path under updatedb/ and passes it to PHP’s file() for line-by-line execution as part of a database migration. An authenticated administrator can abuse this to read arbitrary text files reachable from the web-server process — especially valuable on misconfigured deployments where /etc/passwd, .env, or other sibling-app configs are reachable relative to the AVideo directory.
