In some realistic installations, the POST /test_config (and GET /get_stats) endpoints are accessible through CSRF, and thus an unauthenticated attacker can force the server to send requests to arbitrary internal hosts and ports (including 169.254.169.254) and read a status/port oracle in addition to partial response data.","published":"2026-10-08T05:17:04.000Z","lastModified":"2026-10-08T21:35:54.000Z","status":"Deferred","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":3.4,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N"},"cwe":["CWE-918"],"affected":[],"epss":{"score":0.00162,"percentile":0.05383,"date":"2026-10-26","history":[{"date":"2026-10-08","score":0.00162,"percentile":0.04879}]},"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 (0.16%).
