Nginx itself, however, selects which location block actually serves the request using the percent-decoded, normalized URI. Because the RBAC check never percent-decodes its input, an authenticated low-privilege user can request an admin-only path using percent-encoding (e.g. /%68tadmin.php) and have nginx route it to the restricted location while the Lua RBAC gate evaluating the un-decoded raw string finds no matching restriction and grants access.","state":0,"publishedAt":"2026-10-08T17:32:00.48+00:00","modifiedAt":"2026-10-14T19:35:58.181+00:00","affected":[{"ecosystem":"Vendor product","name":"Malcolm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"CISA\",\n                    \"product\": \"Malcolm\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"26.07.1\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"26.08.0\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/cisagov/Malcolm/security/advisories/GHSA-jr6p-63pg-hr6g","https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-280-01.json"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107334","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107334","identifiers":["CVE-2026-107334"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
