Prior to 0.4.80, the dashboard login rate limiter in src/lib/auth/loginLimiter.js derives the client identity from the attacker-controlled X-Forwarded-For HTTP header, and src/app/api/auth/login/route.js uses that spoofable value for checkLock and recordFail. A remote attacker can rotate the X-Forwarded-For value on each login attempt to receive a fresh rate-limit bucket, bypass the 5-attempt threshold and progressive lockout durations, and perform unlimited brute-force attempts against the dashboard password. This issue is fixed in version 0.4.80.","state":0,"publishedAt":"2026-07-10T15:23:53.709+00:00","modifiedAt":"2026-07-10T16:45:23.879+00:00","affected":[{"ecosystem":"Vendor product","name":"9router","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"decolua\",\n                    \"product\": \"9router\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.4.80\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":7.3,"severity":"HIGH"}],"references":["https://github.com/decolua/9router/security/advisories/GHSA-7cfm-pqrj-xgq7","https://github.com/decolua/9router/commit/7648c3412b403a29f04967c4b4e9725e228791d4","https://github.com/decolua/9router/releases/tag/v0.4.80"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55501","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55501","identifiers":["CVE-2026-55501"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
