The authentication implementation on the xArm controller has very low entropy, making it vulnerable to a brute-force attack. There is no mechanism in place to mitigate or lockout automated attempts to gain access.

Exploit prediction

1.32% chance of exploitation in the next 30 days, higher than 71% of all scored CVEs (FIRST EPSS, 2026-11-09).
