CVE-2019-9950 is an authentication bypass vulnerability affecting various Western Digital My Cloud NAS devices running firmware before version 2.31.174. An attacker can exploit a default empty password for the "nobody" account to gain low-privilege access to the control panel API.

While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high FAUCET Risk Score indicates its potential severity.
