Per a post in the Multiple serious vulnerabilitys including Backdoor etc. as disclosed by gulftech.org discussion.

Per that link:

UPDATE: In a blog post, Western Digital says all issues reported by GulfTech were fixed in firmware version 2.30.172, and not 2.30.174, as Bercegay claimed.

Per the WD blog link:

These had been disclosed by a security researcher directly with our team in 2017, and critical issues mentioned in these recent articles (gulftech.org; thehackernews.com) were addressed in 2017 with firmware update v2.30.172 and above. Minor issues are being addressed in future updates. Additionally, the My Cloud Home model architecturally is designed new from the ground up and we are not aware of any vulnerability to the security issues listed in the respective reports.
