Loki package may skip address check when non-key callback used

published 23 days ago
Summary

The Loki software can fail to verify the source of a connection if a callback other than a public‑key is used, allowing unauthorized access. This bypass lets attackers avoid the usual address validation. Apply the latest Loki update that includes the fix or reconfigure it to use only public‑key callbacks.

What to do
  • Update cleanstart loki to version 3.7.1-r1.
