DEEBOT PRO M1: Active Debug Code
CVE-2026-66403 is a high-severity active debug code vulnerability in DEEBOT PRO M1 from ECOVACS ROBOTICS, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version M1-1.7.27 as the first without the flaw, so updating DEEBOT PRO M1 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update DEEBOT PRO M1 to M1-1.7.27 or a later version.
- Update DEEBOT PRO K1VAC to V1.7.821 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
