CVE-2026-82936

LAN service crash via oversized HTTP bodies

Published Sep 28, 2026 · Updated Sep 28, 2026

Denial of service in F&F Filipowski mH-DEVELOPER before 3.0.30 allows remote attackers on the LAN to crash fh-node with large HTTP bodies. Its Express bodyParser accepts JSON and URL-encoded bodies up to 250 MB, buffering enough request data to exhaust device memory. A crash depends on available memory; the related authentication bypass makes the endpoints reachable without credentials, but the reported consequence is service interruption.
