{"schemaVersion":3,"id":"CVE-2026-26742","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"PX4 Autopilot versions 1.12.x through 1.15.x contain a protection mechanism failure in the \"Re-arm Grace Period\" logic. The system incorrectly applies the in-air emergency re-arm logic to ground scenarios. If a pilot switches to Manual mode and re-arms within 5 seconds (default configuration) of an automatic landing, the system bypasses all pre-flight safety checks, including the throttle threshold check. This allows for an immediate high-thrust takeoff if the throttle stick is raised, leading to loss of control.","dates":{"published":"2026-03-10T00:00:00.000Z","modified":"2026-03-11T14:51:09.728Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.1,"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:N/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00309,"percentile":0.22334,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.043999999999999984,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00265},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00309,"percentile":0.22334}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00265,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00295,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00309,"percentile":null},{"date":"2026-10-10T00:00
