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.","published":"2026-08-13T22:17:23.977","modified":"2026-08-13T22:17:23.977","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/openwrt/luci/security/advisories/GHSA-jf59-v86x-fwf2"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openwrt-luci-app-lxc-acl-inconsistency-authentication-bypass"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T22:17:23.977"}}
