Cockpit: cockpit: arbitrary command execution via crafted links in system logs ui_CVE-2026-4802

{
    "lastseen": "",
    "description": "A flaw was found in Cockpit. This vulnerability allows a remote attacker to achieve arbitrary command execution on the host by exploiting unsanitized user-controlled parameters within crafted links in the system logs user interface (UI). An attacker can inject shell metacharacters and command substitutions into these parameters, leading to the execution of arbitrary shell commands on the affected system. This could result in a complete system compromise.",
