mH-DEVELOPER 智能家居模块存在拒绝服务（DoS）漏洞，源于不可控的资源消耗。该模块使用的 Express bodyParser 将 JSON 和 URL 编码请求体的大小限制设置为 250 MB。局域网内的已认证攻击者可发送大型请求体，耗尽随机存取存储器（RAM）中的缓冲区，导致内存溢出（Out-of-Memory）并引发 fh-node 进程崩溃，从而造成拒绝服务。攻击能否成功取决于设备当前的内存使用情况，而攻击者无法完全控制这一因素。 严重的是，由于 CVE-2026-82930 漏洞的存在，所有端

Vulnerability Title
Denial of Service in mH-DEVELOPER
Source: CVE Program / CVE List V5
Vulnerability Description
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
