What is CVE-2026-73680?
CVE-2026-73680 is a high-severity command injection vulnerability in Cockpit CMS, published on 14 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Cockpit CMS 2.14.0 and prior contains a command injection vulnerability in the FFmpeg integration that allows authenticated users with only the assets/upload permission to execute arbitrary commands by uploading a video file with a shell metacharacter-laden filename. The unsanitized filename is interpolated into a shell command executed via Process::fromShellCommandline() before the slugify() sanitizer runs, enabling injected shell metacharacters such as backticks, $(), and semicolons to escape the FFmpeg command context and execute as the web-server user.
Weakness: CWE-78
