Summary
This vulnerability applies to the Micro Air Vehicle Link (MAVLink) protocol and allows a remote attacker to gain access to sensitive information provided it has access to the communication medium. MAVLink is a header-based protocol that does not perform encryption to improve transfer (and reception speed) and efficiency by design. The increasing popularity of the protocol (used accross different autopilots) has led to its use in wired and wireless mediums through insecure communication channels exposing sensitive information to a remote attacker with ability to intercept network traffic.
Exploit prediction
0.73% chance of exploitation in the next 30 days, higher than 54% of all scored CVEs (FIRST EPSS, 2026-11-08).
