Unauthenticated command injection in AVideo getImage.php
CVE-2026-29058 is a critical unauthenticated OS command injection vulnerability in AVideo / AVideo-Encoder affecting version 6.0 prior to the 7.0 patch. The flaw is in objects/getImage.php, where the application accepts a user-controlled base64Url GET parameter, Base64-decodes it, and interpolates the decoded value into a double-quoted ffmpeg shell command without proper shell escaping. Although the application performs basic URL validation, that validation does not neutralize shell metacharacters or command-substitution syntax, allowing an attacker to inject arbitrary commands. The issue is described as zero-click and network-reachable, requiring no authentication or user interaction.
