CVE-2026-42127 · Pre-authentication denial of service in the public dashboard query endpoint
This page contains facts from public vulnerability sources. Check the original advisory before updating.

This can lead to denial of service through memory exhaustion. No valid dashboard access token or authentication is required to exploit this vulnerability.
