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":"2026-07-10T16:16:33.493+00:00","modifiedAt":"2026-10-25T15:10:00.147+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/commit/7648c3412b403a29f04967c4b4e9725e228791d4","https://github.com/decolua/9router/releases/tag/v0.4.80","https://github.com/decolua/9router/security/advisories/GHSA-7cfm-pqrj-xgq7"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55501","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-307"],"productCriteria":[],"sourceDates":{"published":"2026-07-10T16:16:33.493","lastModified":"2026-10-25T15:10:00.147"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
