An authenticated user can craft a specially formatted request path to bypass role-based restrictions and reach administrative or role gated endpoints they should not have access to. This affects all restricted paths protected by the RBAC authorization layer, including file upload, PHP server, htadmin, and authentication management interfaces.","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":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00977,"percentile":0.61906,"date":"2026-10-26","history":[{"date":"2026-10-09","score":0.00977,"percentile":0.61036}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.98%).
