Loading vulnerability…
CVE-2026-58455 is a critical unauthenticated OS command injection vulnerability affecting Dockwatch through version 0.6.567. The flaw arises from two combined weaknesses: an incomplete authentication flow in loader.php caused by a missing exit() after an authentication redirect, and unsanitized user-controlled input being passed to shell_exec() in ajax/compose.php. By leveraging the incomplete authentication check, a remote attacker can establish the required session state and then supply crafted input to the composePath POST parameter in the composePull action, resulting in arbitrary shell command execution on the host running Dockwatch. In typical deployments, exposure is further amplified because the application commonly operates with access to the Docker socket, increasing the likelihood of full host compromise.
