Mycroft AI mycroft-core version 18.2.8b and earlier contains a Incorrect Access Control vulnerability in Websocket configuration that can result in code execution. This impacts ONLY the Mycroft for Linux and "non-enclosure" installs - Mark 1 and Picroft unaffected. This attack appear to be exploitable remote access to the unsecured websocket server. This vulnerability appears to have been fixed in No fix currently available.

Security readout for executives and security teams

Plain-English summary

CVE-2018-1000621 is an access-control issue in Mycroft AI mycroft-core that may allow code execution through an unsecured websocket server. The provided CVE data says it affects mycroft-core 18.2.8b and earlier on Mycroft for Linux and non-enclosure installs only.

Executive priority

Prioritize any exposed Linux or non-enclosure Mycroft deployments because the issue is remote code execution and no fix is named in the provided CVE data. Isolated or unaffected device types are lower urgency.

Technical view

The vulnerability is described as incorrect access control in websocket configuration, remotely reachable when the websocket server is unsecured. The source bundle does not provide CVSS, CWE, confirmed fixed versions, or vendor mitigation details. It explicitly says Mark 1 and Picroft are unaffected.

Likely exposure

Exposure is most likely on self-managed Mycroft for Linux or other non-enclosure deployments running mycroft-core 18.2.8b or earlier, especially where the websocket service is reachable from untrusted networks.

Exploitation context

The bundle includes a public MycroftAI-RCE reference, but CISA KEV is false and the provided sources do not prove active exploitation. Treat this as publicly documented remote code execution risk, not confirmed in-the-wild exploitation.

Researcher notes

Evidence is sparse: no CVSS vector, CWE, patch version, or detailed vendor advisory is included. The strongest technical facts are affected versions, install-scope exclusions, unsecured websocket access, and possible code execution.

Mitigation direction

  • Inventory Mycroft for Linux and non-enclosure installs.
  • Check current Mycroft project guidance; no fix is named in the CVE bundle.
  • Do not expose the websocket service to untrusted networks.
  • Restrict websocket access to trusted hosts using network controls.
  • Retire or replace unsupported affected deployments where risk cannot be reduced.

Validation and detection

  • Confirm whether the deployment is Mark 1, Picroft, Linux, or non-enclosure.
  • Verify the installed mycroft-core version is 18.2.8b or earlier.
  • Review network exposure of the Mycroft websocket service.
  • Check whether access controls protect the websocket endpoint.
  • Document unaffected Mark 1 and Picroft assets separately.
