No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

An unrestricted file upload vulnerability in Cockpit CMS 2.6.0 allows authenticated users to upload files of any extension including PHP scripts via the asset upload endpoint. The allowed_uploads configuration defaults to wildcard (*) and uploaded files are stored in a web-accessible directory. An attacker with any authenticated account can upload a PHP webshell and execute arbitrary OS commands on the server.
