What is CVE-2026-63304?

AVideo up to version 29.0 is susceptible to an OS command injection flaw due to unsanitized input in the listFFmpegProcesses() function found in plugin/API/standAlone/functions.php. This vulnerability allows attackers to exploit the functionality by injecting arbitrary OS commands through crafted code payloads, resulting in unauthorized command execution as the web-server user. Proper input sanitization and parameter escaping are essential to mitigate this risk and secure the web application.

Affected Version(s)

AVideo 0 <= 29.0
