PX4-Autopilot 访问控制错误漏洞

PX4-Autopilot is an open-source drone autopilot system developed by PX4. PX4-Autopilot has a security vulnerability related to access control. This vulnerability arises from the fact that encryption authentication is not required by default, and when MAVLink 2.0 message signing is not enabled, an...

CVE-2026-32709

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, An unauthenticated path traversal vulnerability in the PX4 Autopilot MAVLink FTP implementation allows any MAVLink peer to read, write, create, delete, and rename arbitrary files on the flight controller filesystem withou...

CVE-2026-32743

PX4 is an open-source autopilot stack for drones and unmanned vehicles. Versions 1.17.0-rc2 and below are vulnerable to Stack-based Buffer Overflow through the MavlinkLogHandler, and are triggered via MAVLink log request. The LogEntry.filepath buffer is 60 bytes, but the sscanf function parses...

CVE-2026-32724

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc1, a heap-use-after-free is detected in the MavlinkShell::available function. The issue is caused by a race condition between the MAVLink receiver thread which handles shell creation/destruction and the telemetry sender thre...
