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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"decolua","product":"9router","versions":[{"version":"< 0.4.80","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","baseScore":7.3,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":3.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-07-10T16:44:55.006800Z","id":"CVE-2026-55501","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-307"}]}],"references":[{"url":"https://github.com/decolua/9router/commit/7648c3412b403a29f04967c4b4e9725e228791d4","source":"security-advisories@github.com"},{"url":"https://github.com/decolua/9router/releases/tag/v0.4.80","source":"security-advisories@github.com"},{"url":"https://github.com/decolua/9router/security/advisories/GHSA-7cfm-pqrj-xgq7","source":"security-advisories@github.com"},{"url":"https://github.com/decolua/9router/security/advisories/GHSA-7cfm-pqrj-xgq7","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
