SCA: security update for wwbn/avideo (GHSA-pmj8-r2j7-xg6c)

high Tenable Self-Hosted Container Security Plugin ID 446654

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - WWBN AVideo is an open source video platform. In versions up to and including 26.0, the
 `sanitizeFFmpegCommand()` function in `plugin/API/standAlone/functions.php` is designed to prevent OS
 command injection in ffmpeg commands by stripping dangerous shell metacharacters (`&&`, `;`, `|`, `` ` ``,
 `<`, `>`). However, it fails to strip `$()` (bash command substitution syntax). Since the sanitized
 command is executed inside a double-quoted `sh -c` context in `execAsync()`, an attacker who can craft a
 valid encrypted payload can achieve arbitrary command execution on the standalone encoder server. Commit
 25c8ab90269e3a01fb4cf205b40a373487f022e1 contains a patch. (CVE-2026-33482)
