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.","published":"2026-10-08T18:17:20.000Z","lastModified":"2026-10-08T21:03:44.000Z","status":"Awaiting Analysis","sourceIdentifier":"ics-cert@hq.dhs.gov","cvss":{"version":"3.1","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00213,"percentile":0.11483,"date":"2026-10-26","history":[{"date":"2026-10-09","score":0.00213,"percentile":0.10642}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.21%).
