Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
PX4 Autopilot versions 1.12.x through 1.15.x can be forced into an unsafe re-arm state when pilots switch to Manual mode and re-arm within 5 seconds of landing, bypassing critical pre-flight safety checks and throttle validation. This allows attackers or malicious pilots to trigger immediate high-thrust takeoff, resulting in loss of aircraft control. …

Vulnerability AssessmentAI
| Exploitation | PX4 Autopilot versions 1.12.x through 1.15.x with default Re-arm Grace Period set to 5 seconds; attacker must have physical access to transmitter; aircraft must complete automatic landing sequence before mode switch and re-arm within grace period window Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 8.1 (HIGH). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker could exploit this flaw, loss of control. |
| Remediation | Monitor vendor advisories for a patch. Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all PX4 Autopilot deployments and identify systems running versions 1.12.x through 1.15.x; restrict flight operations for affected systems to supervised, isolated test environments only. …
