Technical details
The vulnerability stems from uncontrolled resource consumption in Express.js bodyParser middleware, which allows JSON and URL-encoded request bodies up to 250 MB without throttling. An unauthenticated attacker with LAN access can exploit this by sending large payloads that trigger out-of-memory conditions in the fh-node process. The attack's success depends on baseline memory usage, but is practical given the missing authentication (CVE-2026-82930). A patch was released in version 3.0.30.
