Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Aug 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 8 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

If you cannot patch yet, users should consider disabling the debug web server if possible or restrict network access to the device to trusted networks only.

Description

The ECOVACS ROBOTICS DEEBOT PRO M1 and DEEBOT PRO K1VAC models have an active debug web server enabled by default. This debug functionality allows retrieval of floor map and log information stored on the devices. The vulnerability has a high severity score of 7.5 and does not require user interaction or privileges to exploit.

Impact

An unauthenticated remote attacker can access sensitive information including floor maps and logs from the affected DEEBOT PRO M1 and K1VAC devices. This compromises confidentiality but does not affect integrity or availability. The exposure of floor plans and logs could lead to privacy concerns or further targeted attacks based on the gathered information.

Summary

CVE-2026-66403 describes a vulnerability in ECOVACS ROBOTICS DEEBOT PRO M1 and DEEBOT PRO K1VAC where the web server intended for debugging remains enabled. This exposure allows an attacker to remotely access sensitive data such as floor maps and logs stored on the affected devices. The vulnerability is remotely exploitable without authentication and has a CVSS 3.1 base score of 7.5, indicating high impact on confidentiality. No integrity or availability impact is noted. The vendor has not published any remediation or patch information, and the devices are not cloud services, so remediation depends on vendor updates or user action.
