CVE-2026-63305 Details
Description
AVideo through 29.0 contains an OS command injection vulnerability in the ffmpeg.json.php endpoint where notifyCode and callback parameters are concatenated into a shell command without escaping. Attackers who can craft a valid encrypted payload can inject arbitrary shell metacharacters into these fields to execute OS commands as the web-server user.
A command injection vulnerability has been identified in AVideo versions through 29.0, specifically within the FFmpeg JSON endpoint. The issue arises because the notifyCode and callback parameters are concatenated into a shell command without proper escaping. This flaw allows attackers who can create a valid encrypted payload to inject arbitrary shell metacharacters, executing OS commands as the web server user.
To address this vulnerability, both the 'notifyCode' and 'callback' fields should be escaped using 'escapeshellarg()', similar to the existing 'notify' parameter. Alternatively, these fields could be routed through the same allowlist/denylist used for 'ffmpegCommand' to ensure proper sanitization.
