CVE-2026-73680Network attack vectorHinoki check available

Authenticated command execution via unsanitized video filename

Published Aug 14, 2026 · Updated Aug 14, 2026

OS command injection in Cockpit CMS 2.14.0 and earlier allows remote authenticated users to execute commands through video uploads. The FFmpeg asset helper embeds the original upload filename in a shell command passed to Process::fromShellCommandline() before slugification, so shell metacharacters escape the quoted path. An account with only the assets/upload permission can run commands as the web-server user, enabling direct access to application data and service control.
