CVE-2026-4802 is a high-severity vulnerability in Cockpit on Red Hat Enterprise Linux 10 and 9.6 Extended Update Support versions. It allows remote attackers to achieve arbitrary command execution on the host by injecting shell metacharacters via crafted links in the system logs UI. This flaw could lead to complete system compromise. Red Hat has released security updates to fix this issue in Cockpit packages for affected versions.

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.
