CVE-2026-82936 (GCVE-0-2026-82936)
Vulnerability from nvd – Published: 2026-09-28 12:12 – Updated: 2026-09-28 13:31

Title
Denial of Service in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module is vulnerable to Denial of Service due to uncontrolled resource consumption. The Express bodyParser is configured with a 250 MB limit for JSON and URL-encoded request bodies. An authenticated attacker on the LAN can send large request bodies that exhausts buffers in RAM, causing out-of-memory conditions and crashing the fh-node process, resulting in denial of service. The successful attack depends on the current memory usage of the device which is not under full control of the attacker. Critically, due to CVE-2026-82930 all endpoints can be queried unauthenticated, so any user on LAN can perform this attack.
This issue was fixed in version 3.0.30

Title
Use of End-of-Life components in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module ships with an end-of-life, unsupported Debian 8 and Node.js runtime v17.0.1 in its production firmware. This exposes the device to publicly known vulnerabilities that will not receive security patches. An attacker could exploit these known flaws to execute arbitrary code, access sensitive data, or cause a denial of service on the device.
Vulnerable components were updated or hardened, if update was not possible in version 3.0.30

Missing Firewall Configuration in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module does not load any firewall rules at startup. This leaves all listening services, including SSH, HTTP, WebSocket, and Node-RED, fully exposed on the LAN without access control. Any client on the same network can reach every service.

Title
Missing Authentication in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module does not verify tokens in its authorization middleware, leaving all HTTP API and WebSocket endpoints accessible without authentication. An unauthenticated attacker on the LAN can query these endpoints, access system information, and send raw control commands to manipulate building automation devices.

Title
Use of Shared Cryptographic Key in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module uses the same hard-coded SSH host keys on every device, with no per-device key generation. An attacker who extracts these keys from the firmware can set up a rogue SSH server that clients will trust without warning, enabling man-in-the-middle attacks and credential interception.

Title
Undocumented access path in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module contains a hardcoded SSH public key in /root/.ssh/authorized_keys, serving as a potential backdoor. The SSH daemon allows root login via key authentication and starts automatically. An attacker with the matching private key can gain a root shell on any affected device, resulting in full system compromise. The key cannot be removed without remounting the file system and survives a factory reset. Vendor notes that this functionality was used only for service purposes.

CVE-2026-82936 (GCVE-0-2026-82936)

Title
Denial of Service in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module is vulnerable to Denial of Service due to uncontrolled resource consumption. The Express bodyParser is configured with a 250 MB limit for JSON and URL-encoded request bodies. An authenticated attacker on the LAN can send large request bodies that exhausts buffers in RAM, causing out-of-memory conditions and crashing the fh-node process, resulting in denial of service. The successful attack depends on the current memory usage of the device which is not under full control of the attacker. Critically, due to CVE-2026-82930 all endpoints can be queried unauthenticated, so any user on LAN can perform this attack.
This issue was fixed in version 3.0.30

Use of End-of-Life components in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module ships with an end-of-life, unsupported Debian 8 and Node.js runtime v17.0.1 in its production firmware. This exposes the device to publicly known vulnerabilities that will not receive security patches. An attacker could exploit these known flaws to execute arbitrary code, access sensitive data, or cause a denial of service on the device.
Vulnerable components were updated or hardened, if update was not possible in version 3.0.30

Title
Missing Authentication in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module does not verify tokens in its authorization middleware, leaving all HTTP API and WebSocket endpoints accessible without authentication. An unauthenticated attacker on the LAN can query these endpoints, access system information, and send raw control commands to manipulate building automation devices.

Title
Use of Shared Cryptographic Key in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module uses the same hard-coded SSH host keys on every device, with no per-device key generation. An attacker who extracts these keys from the firmware can set up a rogue SSH server that clients will trust without warning, enabling man-in-the-middle attacks and credential interception.

Title
Undocumented access path in mH-DEVELOPER
Summary
mH-DEVELOPER smart home module contains a hardcoded SSH public key in /root/.ssh/authorized_keys, serving as a potential backdoor. The SSH daemon allows root login via key authentication and starts automatically. An attacker with the matching private key can gain a root shell on any affected device, resulting in full system compromise. The key cannot be removed without remounting the file system and survives a factory reset. Vendor notes that this functionality was used only for service purposes.
