CVE-2026-33319Public exploitNetwork attack vector

Command execution via unescaped LinkedIn upload URL

Published Mar 22, 2026 · Updated Mar 22, 2026

OS command injection in AVideo before 26.0 allows context-dependent attackers to execute commands as the web server user via a LinkedIn upload URL. SocialUploader.php passes the API-supplied uploadUrl and a file path into an exec() curl command without shell-argument escaping. Exploitation requires control of LinkedIn's HTTPS API response, such as through a compromised trust path, OAuth context, or API service.
