CVE-2026-73680: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Cockpit HQ Cockpit CMS
Cockpit CMS versions 2.14.0 and earlier contain a command injection vulnerability in the FFmpeg integration. Authenticated users with assets/upload permission can exploit this by uploading a video file with a specially crafted filename containing shell metacharacters. The vulnerability arises because the filename is interpolated into a shell command before sanitization, allowing arbitrary command execution as the web-server user.
AI Analysis
Technical Summary
CVE-2026-73680 is a command injection vulnerability in Cockpit CMS (<=2.14.0) within the FFmpeg integration. The flaw allows authenticated users with limited permissions (assets/upload) to execute arbitrary OS commands by uploading a video file whose filename includes shell metacharacters such as backticks, $(), and semicolons. The filename is passed unsanitized to Process::fromShellCommandline(), enabling escape from the intended FFmpeg command context before the slugify() sanitizer is applied, resulting in command execution with the privileges of the web server user.
Potential Impact
Successful exploitation allows an authenticated user with upload permissions to execute arbitrary commands on the underlying operating system with the privileges of the web server user. This can lead to full system compromise, data theft, or disruption of service. The CVSS score of 8.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict upload permissions to trusted users only and consider additional monitoring or compensating controls to detect suspicious file uploads or command executions.
