CVE-2026-86543
Knowns Management API Authentication Bypass
Halo Surface Signal: 5 out of 5 — more likely to be public-facing.
The Knowns management API, in versions prior to 0.30.0, can be accessed without authentication on all network interfaces by default. This allows attackers to provision public tunnels and re-publish the API at a publicly accessible address, potentially leading to unauthorized access and control.
