{"schemaVersion":3,"id":"CVE-2026-16347","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"MikroTik RouterOS contains a weakness in its API authentication handling that lacks effective safeguards against excessive login attempts. The system does not enforce meaningful rate-limiting, account lockout, or source-based restrictions, allowing repeated authentication failures to proceed without defensive response. In some versions, a fixed per-connection delay is present, but it can be bypassed through concurrent sessions, resulting in continued high-volume attempts. This deficiency increases the risk that an attacker could eventually obtain valid credentials and gain unauthorized access to administrative services.","dates":{"published":"2026-07-28T19:59:29.927Z","modified":"2026-07-29T13:57:56.713Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/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/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00388,"percentile":0.31472,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.12200000000000001,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00266},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00388,"percentile":0.31472}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00266,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00388,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0
