Attackers can send a different forwarded address per request so the limiter keyed on rewritten RemoteAddr never triggers, enabling unlimited password guessing and credential stuffing.","published":"2026-10-07T16:17:47.000Z","lastModified":"2026-10-07T23:17:00.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":6.9,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-348"],"affected":[],"epss":{"score":0.00166,"percentile":0.05838,"date":"2026-10-26","history":[{"date":"2026-10-08","score":0.00166,"percentile":0.05378}]},"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 (0.17%).
