CVE-2026-82929 is a hard-coded cryptographic key vulnerability in F&F Filipowski mH-DEVELOPER smart-home modules. Every device uses the same SSH host keys rather than generating unique keys for each device. An attacker who obtains the shared keys from firmware can impersonate an mH-DEVELOPER device by operating a rogue SSH server that affected clients trust without warning.
