CVE-2026-42127 is fixed in 3 products on 1 platform, first by RHSA-2026:67517, released July 6, 2026. It is not reported as exploited. Patch Radar priority: High.
The public dashboard query endpoint does not limit request body size before processing, allowing unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily large JSON payloads. This can lead to denial of service through memory exhaustion. No valid dashboard access token or authentication is required to exploit this vulnerability.
