CVE-2025-34433Public exploitNetwork attack vector

Unauthenticated code execution via predictable installation salt

Published Dec 19, 2025 · Updated Dec 19, 2025

Code injection in World Wide Broadcast Network AVideo 14.3.1 through 20.0 allows remote attackers to execute code through public APIs. The installation process creates the legacy salt with PHP uniqid(), while public endpoints disclose the installation second and a derived hash that reduce recovery to the remaining microsecond space. With no authentication or user interaction, a recovered salt permits a forged encrypted payload to reach eval() in plugin/API/notify.ffmpeg.json.php and execute as the web server user.
