Hi,
The only official comment so far is this one:
“WD’s My Cloud family of personal cloud products is potentially susceptible to the BASH/ Shellshock vulnerability. WD’s default software configuration and typical deployment for My Cloud devices lowers the risk to this threat. WD takes this threat seriously and is working on a patch to address this issue.”
