{"id":"CVE-2026-107334","published":"2026-10-08T18:17:19.763","lastModified":"2026-10-08T21:03:43.847","description":"Malcolm's nginx Lua role-based access control (RBAC) layer decides whether an authenticated user may reach a role-restricted path (e.g. /htadmin, /auth, /admin_login, /arkime/api/esadmin, NetBox, upload endpoints) by pattern-matching the raw, percent-encoded request URI. 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.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-280-01.json","tags":[]},{"url":"https://github.com/cisagov/Malcolm/security/advisories/GHSA-jr6p-63pg-hr6g","tags":[]},{"url":"https://github.com/cisagov/Malcolm/security/advisories/GHSA-jr6p-63pg-hr6g","tags":[]}],"exploitRefs":[{"url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-280-01.json","tags":[]},{"url":"https://github.com/cisagov/Malcolm/security/advisories/GHSA-jr6p-63pg-hr6g","tags":[]},{"url":"https://github.com/cisagov/Malcolm/security/advisories/GHSA-jr6p-63pg-hr6g","tags":[]}],"hasPoc":true,"ai":null}
