CVE-2026-29058: WWBN AVideo is vulnerable to unauthenticated OS Command Injection via base64Url in objects/getImage.php

Severity: Critical

CVSS Score: 9.8

AVideo is a video-sharing Platform software. Prior to version 7.0, an unauthenticated attacker can execute arbitrary OS commands on the server by injecting shell command substitution into the base64Url GET parameter. This can lead to full server compromise, data exfiltration (e.g., configuration secrets, internal keys, credentials), and service disruption. This issue has been patched in version 7.0.
