CVE-2026-66407: Use of a broken or risky cryptographic algorithm in ECOVACS ROBOTICS DEEBOT PRO M1
DEEBOT PRO M1 and DEEBOT PRO K1VAC improperly implement authentication in WebSocket communication. The WebSocket private key may be retrieved through analyzing the traffic data via a man-in-the-middle attack, and communication contents may be altered.
AI Analysis
Technical Summary
CVE-2026-66407 describes a vulnerability in ECOVACS ROBOTICS DEEBOT PRO M1 and DEEBOT PRO K1VAC where the authentication mechanism for WebSocket communication is improperly implemented using a broken or risky cryptographic algorithm. This flaw enables an attacker who can intercept network traffic to perform a man-in-the-middle attack, extract the private key used for WebSocket authentication, and manipulate the communication data exchanged between the device and its controller or server.
Potential Impact
Successful exploitation could lead to disclosure of sensitive authentication keys and unauthorized modification of WebSocket communication data. This compromises confidentiality, integrity, and availability of the affected devices' communication channels, potentially allowing attackers to control or disrupt device operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time.
