CVE-2026-72842
luci-app-lxc contains an ACL inconsistency vulnerability that allows low-privileged authenticated LuCI users to access backend container management routes without proper authorization checks. Attackers can exploit path traversal via `/.%2E` in the `lxc_name` parameter to escape container directories and control host-side scripts executed through `lxc.hook.start-host`, achieving root code execution on the OpenWrt host.
