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.","state":0,"publishedAt":"2026-08-13T21:54:41.307+00:00","modifiedAt":"2026-09-30T17:20:24.61+00:00","affected":[{"ecosystem":"Vendor product","name":"luci","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"openwrt\",\n                    \"product\": \"luci\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThanOrEqual\": \"24.10.8\"\n                        },\n                        {\n                            \"version\": \"25.12.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThanOrEqual\": \"25.12.5\"\n                        }\n                    ],\n                    \"modules\": [\n                        \"luci-app-lxc\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/openwrt/luci/security/advisories/GHSA-jf59-v86x-fwf2","https://www.vulncheck.com/advisories/openwrt-luci-app-lxc-acl-inconsistency-authentication-bypass"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72842","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72842","identifiers":["CVE-2026-72842"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
