{"schemaVersion":3,"id":"CVE-2026-35491","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"FTLDNS (pihole-FTL) provides an interactive API and also generates statistics for Pi-hole's Web interface. From 6.0 to before 6.6, Pi-hole FTL supports a CLI password feature (webserver.api.cli_pw) that creates “CLI” API sessions intended to be read-only for configuration changes. While /api/config correctly blocks CLI sessions from mutating configuration, /api/teleporter allowed Teleporter imports for CLI sessions, enabling a CLI-scoped session to overwrite configuration via a Teleporter archive (authorization bypass). This vulnerability is fixed in 6.6.","dates":{"published":"2026-04-07T15:00:11.079Z","modified":"2026-04-07T17:52:48.043Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00173,"percentile":0.064,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.017,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00156},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00173,"percentile":0.064}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00156,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score"
