Klever-Go: /log controls global node logging
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
An unauthenticated client can connect to `GET /log`, send an arbitrary logger profile as the first WebSocket message, and mutate the node's global logging configuration before receiving live logs from the process. I confirmed this against a local validator built from this repository: an unauthenticated client set the global log level to `*:NONE`, the node accepted the profile, and the node stopped emitting normal slot logs while the WebSocket connection remained open.

Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
